Hanson and his wife Natalie first met in 2000, and were married two years later.
That same year, the new couple welcomed their first child, a son named Jordan, who was born on Halloween.
Not long afterwards, the pair added three more sons and two more daughters to their family. Maybellene is the newest member of the brood.
In a recent interview with People, Natalie explained her name-selecting process and how she preferred to use ones that were nontraditional or had not been used in years.
