First we continue our life stories season, with celebrating life at 117 welcome to my great grandmothers 117th birthday. Right now, she is taking pictures of people who have come to see her and celebrate this big day with her. There is more than 90 years difference between me and her. Shes 117 and i am just 23. I am priscilla ngethe. I am returning to my ancestral home in kenya to celebrate a remarkable birthday of one of the oldest people in the world. My great grandmother, elizabeth koinange. I am here to discover the secrets of her long life, as she throws a party and reunites five generations of my family. This is kiambu, where i was born. Its about ten miles from nairobi, the capital of kenya. This fertile land has been home to the kikuyu tribe and to my family, the koinanges, for at least six generations. Today, there are hundreds of koinanges like me, spread around the world. I am returning from my home in london to visit a woman very close to my heart. Who has never left kenya, but has cultivated a global family. We arejust heading up to my great grandmas house. The road is quite bumpy because it is, like, a makeshift road. This is a shrine where most of my family are buried, my great grandad, my grandad, his children and his five wives. My great grandmother is the fifth wife out of six. Were heading up to my great grandmothers home, she lives right by the side of where my great grandad used to live and im really excited to see her. Here she is. Hi hello how are you . Im fine. It is good to see you. Good to see you. She is fine. Long time. Long time, many years. This is my great grandmother, Elizabeth Gathoni koinange. She is going to be 117. This is my great aunt irene and she is here to help with the translations, because i can understand everything my great grandmother tells me, but to speak kikuyu is really difficult. Great grandma elizabeth has lived on this land for 90 years. She grew up tending cattle on her fathers farm, then moved here as a young bride and raised seven children. She built this house with profits from the farm. My great grandmother is proud of her government identity card. It doesnt show the exact month or day that she was born, but does have her year of birth as 1900. The kikuyu tribal tradition of age groups gives the same name to all children born in the same year. My great grandmother belongs to the kihiu mwiri age group, meaning we know she was born sometime between 1899 and 1900. Do you remember when you got married . And how do you remember your wedding day . Is it force . Force. She was brought by force, she was married by force because she was too young. Yeah. And at that time she didnt want to get married to an old person because she was the fifth wife. Great grandmother elizabeth was the fifth of six wives of the senior chief koinange. He worked with the british during colonial rule and is well known in kenya for playing a part in the countrys independence. So was it difficult for you to be the fifth wife . Leonard is elizabeths sixth child and he is my great uncle. He lives next door to my great grandmother and was a child during the 1950s, when his father, senior chief koinange, was detained during the mau mau uprising. The mau mau uprising was a revolt against european ownership of land. Archive mau mau suspects were being checked prior to interrogation, all were members of the kikuyu, the tribe which has suffered most from the mau mau. A state of emergency was declared in kenya and although it eventually led to the end of british rule, it was a tough time for my great grandparents and for my uncle leonard. In 1952, my father was taken into detention. Kenya had been declared emergency and he was detained for the next seven years he was in detention. We used to be children of a chief, we became beggars. We were being helped by those people we would have called poor. During now the mau mau, it was not only affecting our family, it affected other families. One of my aunties, who had, i think there were nine children, my mother took them and already she had taken two other children who belonged to her sister who had died. My mothers sister. So, my mother was raising about 20 children. So we had a lot of. It was chotic, you know . Like, we are fighting for food. This shrine is the resting place of my great grandfather. He lies alongside his five wives and there is a space reserved for my great grandmother elizabeth. As theirs was a polygamous marriage, visiting this shrine puts into perspective how large the chiefs family really was. My great grandfather is resting here. But his legacy is living on in hundreds of descendants. What do you think about polygamy today . Would you advise me to go down that route . You wouldnt like me to, no . You were the last one to practise polygamy, does that mean that our family will now be smaller and smaller and how do you feel about that . So you wouldnt want me to just have one or two kids, you would want me to have five, six. Regardless of how many children i may have in the future, there is no doubt that the family is growing. My great grandmother gave birth to seven children and there are tens of grandchildren. My father was one of them and i am his second child of three, making me one of many, many great grandchildren to elizabeth. Who is in those pictures, that one there . And is that you . So pretty that picture there, the one, i think its you and those kids around you. I can see that photographs play a big part of my great grandmothers life. To celebrate her birthday, she is throwing a party. And we are going to attempt something very special. A family photograph, a living family tree, with five generations of my family and my great grandmother at the centre. But with so many people involved, it could take a while. The 1st of january is a big day for my great grandmother, elizabeth koinange. She has invited family and friends to celebrate her 117th birthday. They have travelled far and wide and it is a chance for me to reunite with my kenyan family. So your family, your children, childrens children, they are all spread out across the world like me in london. Do you like that we are all over the world . So have you always celebrated on the 1st of january, since you can remember . Right now, everyone is preparing the food. There is going to be loads of meat, loads of vegetables. So now its time to get changed, all the guests are slowly arriving so i will wear something that is a bit more comfortable. By throwing this party, my great grandmother is continuing the tradition started by her late husband, of gathering friends and family together on the first day of the year. So right now, the party is in full swing. Most people have eaten. There are still some people getting served over here. We still have some late arrivals coming in, as youd expect. We have my great uncle right now giving a speech and saying once everyone has eaten, the whole family, everyone gets together and takes a Group Picture of the family tree. Next, its time for the guest of honour to take the microphone. Time for cake, and one of elizabeths granddaughters does the honours. Happy birthday. Happy birthday great grandmother puts her longevity down to a diet of yams and milky tea but for today, she is happy to indulge. Shes been given some cake and the first people to be given some cake was everyone named after my great grandad. So what my auntie said was, all the koinanges, come and give your grandmother, you great grandmother, your great great grandmother some cake and i think she is happy, she has had a lot of cake. Hopefully when im old and 100 years old, i will be fed cake by all. All the people who come after me. Its a beautiful thing and im quite jealous, to be honest. So we are just going to wait. Im going to choke. This cake is good. So we are just going to wait for my great grandmother to go to where they are all taking a family picture. Once we are all sat down, we will start will move into that area. 0rganising so many people is a tough task. Everybody is keen to catch up. And while great grandmother patiently waits, it is a chance to meet relatives i didnt know ihad. Do you know how we are related . I belong to the grandmother. He is my cousin. So his son is your dad . Hello. Hi, hi, hi. Thank you very much. Lam youraunt. People are so excited to see each other that they are socialising and they are slowly, slowly, slowly moving towards this way. So hopefully we get the picture by the end of the day. First to join our living family tree, great grandmother elizabeth. Surrounded by her six surviving children, who have a combined age of more than 400. Next to join, my aunts and uncles. So now another generation has been called, for whom she is their great grandmother, so i nowjoin. My mother has been holding this party for about 20 years. She enjoys it. She would like to do it every quarter of the year. She is happy to see her family coming together. She has created a great family unit. Camera clicks applause many of us enjoyed tracing our family tree but for most families, gathering so many generations like this together is impossible. Its no surprise that people have travelled from far and wide because great grandmother elizabeths enthusiasm for life is infectious. I finally got my selfie. Hers is a life well lived, a life focused on providing her descendants advantages that she didnt get to enjoy. Faith, love and food are the fundamentals of my great grandmothers life. And although she rarely leaves her small house, the world comes to her, through her children, grandchildren and great grandchildren like me. One of the things which i like about her, and i think this is god given, is her memory because she doesnt get old. If you come here, you say hello to her and talk to her, next time you come, she will remember you very well. She cant forget. Bye improvements in medicine mean we can all expect a longer life but its how you live it that really matters. And for this, my great grandmother elizabeth is my inspiration. Hello there. It was a sparkling sunday for many of us. A hard frost yes, but some beautiful blue sky and sunshine for most, anyway. Temperatures in the glens of scotland got down to lows of 10 degrees. We saw some beautiful weather watchers photographs showing the frosty scenes with the lovely blue sky throughout the day. However, there are signs that the cold air is going to slowly be squeezed out by something a little less cold moving in from the atlantic over the next couple of days. Monday will give a north south divide from many in terms of sparkling sunshine through scotland, Northern England and Northern Ireland. An easterly flow will drag in more cloud across england and wales, producing a little bit of nuisance drizzle as well, making it feels cold and drab for much of the afternoon. Top temperatures on monday 2 6d, down on where we should be for this time of year. As we move out of monday, the winds will start to fall light, and drizzle will ease away. But could be some problem with some fog forming, some a bit dense in places and if that happens, it can be pretty slow to clear away first thing on tuesday morning. Not quite as cold on tuesday but with the fog around, is not going to feel particularly great up there first thing in the morning. Hopefully, the fog will slowly lift away and tuesday is a sign of a slight change developing. A waterfront pushing in from the atlantic. Ahead of it, we see the winds swing round from a southerly direction. That will give something a little less cold which means this will be rain rather than snow. But at the same time, we have the south easterly flow dragging in more cloud along the east coast of scotland and eastern england, 3 5d at the best. Milder a little bit further south and west, but indications of the wetter weather set to push through. That will arrive overnight tuesday and move into wednesday. For a time, some of it along the west facing coast will be quite heavy as well. This weather front is going to make what we call erratic progress as it pushes further east, its going to be a really messy picture as we go through the day. The rain lingering across much of the eastern half of the uk. Behind it, slowly we will see an improving picture, brighter skies, sunshine into Northern Ireland and the western fringes by the end of the afternoon, and here, double digits quite likely. As we move out of wednesday into thursday, we see this brief ridge of High Pressure developing, the isobars open up and the winds falling light yet again. At this time of year, again that could produce some problems with fog, particularly with the moisture still lying around as that frontal system clears away. A foggy start to thursday, there could be rain in the north east, the fog will lift and hopefully we will see sounds sunny spells with highs of around 5 7d. As we move out of thursday into friday, we see another weather front starting to push in from the atlantic. This could potentially herald a change to the longer term picture because we start off pretty cold, but quite settled. As we look further ahead, it looks like the jet stream will likely intensify entered across the uk which will drive these areas of low pressure in from the atlantic. So all that basically means as things could turn a little more unsettled as we move towards the end of the week into next week. Generally, quite unsettled with rain at times. There will be some drier interludes. With the rain, we could see gales as well. Temperatures improving a little but dont expect too much, average for this time of year. More details coming up throughout the week. Tonight at ten, theresa may defends the governments handling of the nhs, as she prepares a cabinet reshuffle. 0utlining her plans for the new year, she insists the Health Service is performing better than before, but admits nothing is perfect.
