i don't have a ton set in stone except for his dad so you'd have some flexibility on your end/we can brainstorm- but his first wife (tibs' mom) died suddenly in '93 from an aneurysm, and he remarried three more times between 1998 and 2016. he was a lobsterman with a penchant for alcohol and a tendency to cheat so those relationships usually ended pretty messy... but he kept getting married bc he's one of those blue collar guys that likes having somebody to come home to/take care of him. the specific part that matters to fill the line is just making sure your girl has a mom that would fall for a guy like that (probably handsome but pretty low income, saddled with a son, bit of a temper etc)
basically if this interests you at all i can make us a custom idk why i'm writing a novel at you lol
