We have loads of group photos of my family; both my mother's and my father's side.
The first is my mothers' side; Gran and Grandad, all my uncles and aunts (though 2 uncles have remarried) and all the cousins but one. Those of us here are all within 4.5 years of each other; the last one didn't arrive until the youngest of this group was 10. Note the cat snuck in? Albert, I think. January 1981; I'm front left in the blue dress.
Here is the same family again 3 years later; I'm in front of Gran, wearing a white tshirt.
And here is my father's side in January 1985. Grandma, Grandpa and all aunts, uncles and cousins present; amazingly the only change since this, in January 1985, was the loss of Gaandpa 3 years ago! I'm in the front, to Grandma's right.
