She has one sibling (younger) and two step-siblings (one older, one younger). I'm thinking only one of them is a brother so they'd be three girls and one boy. Frances grew up outside of Boston, then moved to California in 2009 and worked as a photographer. In the meantime, I'm thinking her mom and step-dad moved from MA to Portland for the step-dad's job, so the kids could either have followed if they wanted a fresh start or not. In late 2016, she had a mental breakdown and essentially abandoned her life in LA to move to Portland to work on recovering from her depression. She's been living on the ground floor of their parents' duplex and working for a florist to try to regain some stability. She's pretty much been a hermit since she moved to Portland but she's starting to come out of her shell. I would love a sibling line that's sort of been her only friend or connection point other than her therapist and her mom.
I'm really flexible on how close they are, I'm undecided on whether they grew up together in Boston or whether the step-siblings grew up with their mom so I'm open to discuss that. But if Cybille has kids, maybe that was another draw to Portland for Frances because she could be more a part of their life now. (Also I LOVE Mila and Emma and would die to have them be Frances' nieces.)
