The picture belongs to a woman – my father's 2nd cousin found through DNA matching – and she says it's her grandfather, who was a Frenchman. She was never told the man's name, and we are trying to find his identity – and believe it is one of my ancestors.
I had a great grandfather who was a Sergeant in the 1st Regiment of Zouaves in 1854, but this picture appears to be dated much later, so I don't think it was him. I don't have the date for the picture, but guessing somewhere around 1890–1900.
I posted another picture of him as an older man – also wearing a uniform – with a number 108 on the collar.
Any leads would be much appreciated.
