My mother was one of 8 kids and my father one of 10. I have a myriad of aunts and uncles…all who survived to adulthood got married and had kids, all but one of my dad’s brothers who I don’t think was gay, but who never moved out of his mother’s house, and who died 18 years ago. Every single other person on either side of my family had kids, some as many as 4, some as few as one. They all seem to be married or dating now and I have not heard anything about any of them being homosexual. Most of my cousins now have at least one kid, I have one who has like 6. There is one I haven’t seen in years who might be a closet homosexual…he kind of fit the profile a bit, but I’d heard he dated women, so if he is, he’s not out. I know my parents both have larger extended families as well, my dad knows a lot of his cousins still and as far as I know none of them were/are, and my mother has 4 half siblings and none of them as far as I know is or has any kids who are. The grandkids of my parents’ generation are mostly too young to have started dating, so I gotta imagine somewhere in there, probably someone is, but if so, I don’t know who.
However, my wife was an only child, but her father had 2 other kids from a 2nd marriage, one of whom, her ½ brother, is gay…he and his partner of many years are planning a wedding in Iowa next June. Her parents were each one of 4 siblings, and on her mother’s side, one of her mother’s sister’s kids (her first cousin) is also openly gay. They both were closeted for a while and both came out since I met my wife. So, even though her family is MUCH smaller than mine, she has 2 gay relatives by blood and I don’t have any that I know of. It’s just one of those things, you never know….you could have two people who come from tiny families produce a gay child and you could have a family where everyone has a dozen kids and no one ever turns out gay.
