A WELL-KNOWN and much-loved Port Seton stalwart is celebrating her 100th birthday today (Friday). Margaret Mack, of Thomson Crescent, was set to enjoy her special day with plenty of video calls with her family, after the coronavirus pandemic forced her to put plans for a party on hold. Born in Port Seton on February 26, 1921, Margaret attended Cockenzie School as a child. She met her late husband Charlie, a miner, in 1938, when they both attended the now-disbanded Prestonpans Wheelers bicycle club. The group would cycle to places such as Dunbar and Peebles for the afternoon. Charlie owned a tandem bicycle with his brother and an intrigued Margaret asked him to take her for a short ride along the coast.
