I thought of cousins because my sister's family all live in the same town.
Abs went to the same school that both her Aunts went to (ME! one of them anyway) and three cousins. Okay they had different surnames.
It's strange for me, because my Dad was almost of a different generation than his brother; my cousins are so much older than me (and live in London). I didn't have an extended family growing up and felt a little rootless because of it. It affected my sister too, only with her it made her determined to put down roots.

Of course Abs has twin boys now, and in fact they have twin cousins on their Dad's side. All conceived naturally. They're unlikely to end up in the same school just because of the way County lines are drawn. But they may be in the same school as their mother's aunt's youngest child (I am rubbish at proper names for family ties) because they are only a few years younger.
