So the sister were, Agnes born 1896, Elizabeth 1901 and Maggie 1910
Would that match ?
In your first post you wrote:
We think the photo is of the Scottish side so grandads mother Maggie jamieson born 1910 and her sisters or Maggie's mum Annie Mcdonald born in 1878 and her sisters
Are you saying that Annie's daughters were Agnes, Elizabeth and Maggie, born between 1896 and 1910?
What I was wondering was, if dobfarm could be right about a WW1 date, when were Annie's sisters born? (Alternatively, might the photo be of Annie with Agnes and Elizabeth?)
