William was born April 12, 1922, in Passage West, County Cork, Ireland, to William Joseph Mostyn Sr. and Catherine (Cotter) Mostyn. He was born in Ireland and emigrated to the United States with 6 siblings and his mother by a weeklong sea journey to meet their father who had emigrated previously. William grew up with his family in South Boston, where his music loving family hosted many parties full of Irish music and songs which invoked so many happy memories for him. After high school he worked in the Charlestown Shipyard but as the U.S. entered World War II, he enlisted with his friend to the Naval Air Corps. Near the end of the war he was stationed at the South Weymouth Air Base where he met his future bride Catherine Lord. William and Catherine settled in Abington while he started his family, worked at the Industrial Accident Board and graduated from Northeastern Law School. William and his young family moved to Wollaston and remained there for several years as their family began to grow. The family then moved to Abington, where William opened his own law practice and worked as the Veteran's Agent for the Town of Abington, a position he held for nineteen years. William was also the head of the town Democratic committee, a member of the St. Vincent DePaul, the Knights of Columbus and a faithful communicant of St. Bridget's Church in Abington and the Our Lady of Lourdes in Wellfleet. Upon retirement Bill and Catherine moved permanently to the Eastham home that they owned. Bill and Catherine enjoyed retirement on Cape Cod, wintered in Naples, Fla., and travelled extensively all over the world. For the remainder of his life, Bill continued to travel, bowl, golf, walk, read, attend Holy Cross College football games, swim and spend as much time with his family, who were the center of his world.
