My family is a bit smaller but
'60 - grandma, mom, me and two sisters
'70's and '80's, me mom, two sisters+husbands, my husband, four kids=11
90's I woke up and left, my four kids came with me, ex-husband out but still thinks it's the truff
My two sisters and one bil are left, no kids. Sweet! Three left.
I hadn't looked at it this way before!
