Thanks Jan and Findem
I've been working on the theory of H_ (de) la S_, also H_ (de) la L_
I've considered Hen_, Herm_, Hero_
I've tried Serra, Sena, Sera, Lerra, Lena, Lera
--- if only he was someone really famous ... Google doesn't really help if you have no idea what the name is, but I have tried all sorts of combinations
All I can tell you is that he was French (unfortunately, where in France he was born I have no idea), b c1837, a writer (what kind of books/articles, I have no idea), he was Catholic
I tried looking for deaths in Hackney between 1901 and 1911, but there are a lot ... and not really having an idea of the name (either first or last) ... and he could have decided to return to France, or move elsewhere in the UK/world
I tried looking for him in other censuses ... but ditto the above
Think I am stuck
