Sharing Pictures

My father-in-law died last week and my husband and I found loads of pictures. Most of them had nothing written on the back and we have no idea who they are. The little girl against the house is Margaret Elizabeth Baker, age 10 month forn Feb 1st 1917. The other picture looks like it might have been taken maybe at a fair. The back has (J.J. Wolf The leading Photographer Lancaster Ohio. Duplicates can be had at any time.)
I don't know if copy rights ever run out but my father-in-law was 93 when he died and since my mother-in-laws family wasn't from Lancaster I have to assume it was from Ed's side of the family.
