Hiya China!

Just been looking at the link Em posted (thank you so much

) and if I'm reading it correctly, he was a photographer
before 1900 which could explains the old stock I guess. For this to be the family of four I think it is, then I need it to be around 1901-1902 as the ages I need the children to be based on DOB are:
Girl 12 years; Boy at back 10 years; Baby 18 mths - 2 years; boy 8 years.
1905 throws me through a loop completely unfortunately.

Yes, happy little bunch aren't they, but if they are who I hope they are, then their world crumbles as they are split up, when the parents (not married BTW) no longer live together. The two at the back having a different mother (dec'd) and they stay with their father and the two in the front, go with their mother.
