What is the largest number of children in a family that you know, personally, and how do you know them?
One of mine and DH's best friends is the oldest of 6 kids. My grandfather was also one of (about) 9, but some of them died before I was born and I know even less of them.

Re: S/O Duggars, a poll.
I'm the second of 6.
DH's Gma is one of 9.
I have a friends who have 12 children.
A family that are patients at my work have 12 kids...
people I REALLY know? My BIL is one of 10 and my stepmom is one of 9! Irish Catholics... LOL!
My family used to go to church with a family that had 10 kids. When the oldest got married the youngest was 2.
Another family had 8 kids, the oldest was my age (from a previous marriage) and then 7 with her second husband. All of the kids have J names...and they are all stunning!
I have a great aunt with 16. I can name about 11 of them. The youngest is about 4 years younger than me.
