Robert Langley Porter (b. 26 Sep 1870)
Searching for ancesters of Robert Langley Porter, b. 26 Sep 1870.
Family lore has it that Robert was adopted, possibly by an American named Porter, which leads one to suspect that his birth name might have been Langley.
Robert later studied medicine at Guys Hospital, London, so it's possible that he may have been born in Britain.
At one point, he was a Canadian citizen, so it's also possible that he was born in Montreal, Quebec.His descendants consider this the likely case.
Any help would be greatly appreciated.
