I just wish I had some pictures of my mum's side of the family, other then one photo of my grandfather as a boy, and a contemporary one of my grandmother, I don't have any. I only ever knew my grandfather aswell, it would have been really nice to see what my grandmother looked like in her hay-day.
As for my father's side, I have a few photos of my grandmother, but have no idea what my grandfather looked like, he died when my father was 3mths old and the only pictures he had of him were stolen when his house was broken into long before I was born.
I have photos of my paternal grandmother's side of the family though that I keep with me which I am very grateful for!
