It’s hard to work out who R. Hartman is – it’s an unusual surname, and there are no R. Hartmans in the English birth index who fit. He may be Andrew Robert Hartman, born in 1875 in Germany, and living in London in 1911 (still single) but I wouldn’t stake anything on it. However, I would guess that he was born abroad.
