He sure looks like a Jacques to me. Which is not too imaginative I know, but he looks like a Jacques. Or maybe an Emile.
If you want something more unusual...
the site
www.prenoms.com allows you to do a search for the most common and unusual names by year...and goes back to 1901, sorry can't get you closer to that but it was still the 19th century at heart in 1901...take a look at those see if something strikes your fancy
and you can go by region and year - this guy looks to me like he should be from like the Franche Comte or Savoie or somewhere over there
maybe even Geneve, maybe he's French-Swiss
there's a list of last names, ordered by popularity, you can browse there for ideas too
or try meilleursprenoms.com under the heading regionaux...there are some interesting different ones in there
the organization's a nuisance for browsing, you have to choose each letter, but there are some unusual choices there
maybe he's from provence - have a look at those
if you want something specific translated, send me a message
