Just to follow up again ( I wish we could edit original posts)
I found more for Francesco Ferrari( turns out only a small amount of the time called Francois) It appears he may have been Swiss, Ticino, married a Domendietti from Ticino, probably Dangio.
Any Swiss Ferrari families out there that we may link to?
Vincenzo Ferrari born pre 1830 -possibly Ticino Switzerland Vincenzo died pre 1890
had son Francesco Ferrari born 1846 -possibly Ticino Switzerland married Marina Domendietti in 1890 from Ticino Switzerland witnesses G Copanella & A Rabaiotte Francesco died at the French Hospital Shaftesbury Ave 1898
