My little branch of the family moved 2,000 miles away from most of the rest of it when I was less than a year old. I have a first cousin 5 years older than me, a first cousin 20-something years younger than me (half-sister to the other cousin, if I remember correctly, but I’m not even sure o the kid’s sex), and a first cousin once removed (also basically an infant and I think also a girl, but again I’m not sure.) I’m sure I’ve got plenty of other second cousins, third cousins, and so on, but I quite frankly don’t care. Heck, I haven’t even seen either of the recently-born cousins I have and I don’t think I’ve seen my older first cousin in more than a decade. I’m sure I’ve met some second and third cousins of various levels of removal at “family reunions” where the only link between me and them were my paternal grandmother. So, needless to say, I generally think of myself as having basically no extended family.
Heck, for that matter, I think I’m distantly related to people I just think of as friends of my parents. I’m probably third or fourth cousin to them, but again it’s never come up.
