My younger first cousin is a lesbian and also my uncle's (her father) ex-wife is now with his current wife's sister.

She's not blood, but my family
adores her and I've always referred as my aunt even long after their divorce. It works tho and everybody's happy with the exception of their son who is lowkey upset about his mom being a lesbian, but oh well; he'll live.
I also suspect a younger male cousin to be gay, but I don't have anything concrete aside from observed behaviors and my gut feeling; I wouldn't be shocked if he ended up coming out in a few years.
