If we go by people that I know how they are related to me, I know my great aunt and uncle’s grandchildren. I would usually call them third cousins, but I’m not sure that is correct.
However, for a long time, I attended a family reunion that went to my maternal-maternal great-grandmother’s family, and met a lot of people who were related to me through her. We never really did try to figure out exactly how we were related, but we have always considered ourselves related–to the point where my grandpa had to point out that the woman he is now romantically involved with is not related to me, despite having the same last name my great-grandmother was born with.
BTW: the great-grandmother in question died less than a month before I was born.
I hang out with my… removed cousin(?) or twice removed cousin(?) from time to time now that I’ve moved to Toronto. Our dads were cousins who were about the same age and they were good friends when they were kids and spent a lot of time hanging out on my grand dad’s farm. But as adults our families barely ever met up due to geography. I think there’s like a 20 year gap from when my sister and I hung out with our removed cousin(s) on a family trip and then met up again in the 1990s.
Now we live only 5-10 minutes away from my twice removed(?) cousin and see each other a few times a year.
I recently discovered I am friends with the grandfather of my 1st cousin, twice removed (that’s right, I think - my cousin’s grandchild).
Real weird situation - TheKid took a craft class at a local store, I knew the teacher’s husband (I work with him). She was talking about something that happened with her daughter and newborn child, referred to the baby daddy by his last name. Erm, that’s my last name. Did a little verbal family tree, yup. We’re related. Vaguely.
Never met my baby cousin, though. Haven’t seen his dad in five years.
I’ve known packs of cousins of varying sorts, as I went to high school in the small rural town in Mississippi in which my mother’s father’s family has been entrenched since the 1830s or so. I liked to joke that our town only had four last names, and my maternal grandfather’s surname was one of them. That’s a little extreme, but all the major families of that area are intermarried with each other, sometimes several times over. Additionally, my great-grandfather had 18 children (by two wives).
Off the top of my head, I used to know my great-grandmother’s sister’s granddaughter (third cousin?) fairly well, as she was close to my aunt. I know I went to HS with lots of people who were second, third, fourth, fifth cousins, etc.
I have a ton of first cousins – over 30. I am close to some of them, but barely know others – my mother was one of 11 kids, and among the younger ones, so I barely know her oldest siblings, much less their kids.
I casually know a few first cousins once removed (children of my cousins), and met some of my father’s cousins (also first cousins once removed, I believe) when I was a kid, but haven’t seen them in decades.
AFAIK, I’ve never met any of my relations who are more distant than that.
