Richard (1861-1938, died in Paris, France) from the Thalmann family of Mannheim (in south-west Germany) had about four siblings:
- Ernst (founder of Ladenburg-Thalmann Bank in NYC in 1875),
- Flora (later Rosen), and
- two(?) others.
The parents were, according to Richard's marriage records (Paris, c. 1894) named Wolf and Amélie, although this may be a francophonisation.
How could I find a marriage record for Wolf and Amélie?
