Looking through family photos recently, I came across one that surprised and intrigued me.
My mother was one of three children (Iris, Jean and Allan) all of whom had children: 4, 3, and 4 respectively, which makes 11 grandchildren in total.
Now, Allan's family lived in Dunedin, we lived in Wellington, and Jean's family lived in a number of places in the South Island, so, although we had contact we didn't ALL get together at one time and place.
Except once, as the photo below attests.
L to R: Ron (1.2), Bryan (1.4), Elisabeth(3.3), Robert (2.3), Craig (3.4), Tony (3.2), Kay (2.2), Graham (3.1), Barbara (1.3), Ian (2.1), Louise (1.1).
As far as I know that is the only such group photo in existence.
