She's lovely and I can see the resemblance in you.
I absolutely love my old family photos.... here are a few of my favourite (I was being restrained - there are too many!):
This is my Grandma as a baby in 1918. I just love the lace on her dress!
This is my Great Aunt Joan at the beach in the 1940s:
This is Great Aunt Joan. Grandma had written on the back "I don't believe Joan likes having her photo taken unawares". I don't know why, but it's one of my favourite photos.
Grandma wrote that this photo was taken on Christmas Day, 1940. My Grandma is second on the left. The little boy on the far right is Terry, an evacuee from England that Grandma's family looked after. The older men are Defence Force members - Grandma's family were "respite hosts" during WWII. Between deployments, defence members would stay at Grandma's house and they would take them out on recreational trips (it's how she met my Grandpa!)
I love that your grandma has an arnotts milk arrowroot biscuit on her high chair tray in 1918! some things never change.
and I love that swimsuit on your great aunt Joan.
