Thank you all for your gorgeous 'fixes' and comments - the four men are Irish, I think the photo may have been taken in Wexford or Kerry, but definitely Ireland. I think the man second from left is William Huggard, who was a Customs & Excise Officer and therefore moved around a lot - his five children were all born in different counties. The man at the far left is Martin Huggard, my great grandfather, who qualified as a solicitor in 1865 (hence my feeling that this photo was maybe to celebrate that?) William's son, the other two are Williams other two sons, William (the boy in the photo) and George. So William's two daughters and his wife were not included in the photo. Prue, do you have any thoughts on why the background would have been removed? I recall seeing the original photo and it was the same.
Thanks again everyone - you're all brilliant!
