Joseph Guggenheim and his wife Francisca were living in Pesta, Budapest, Hungary, in 1820. They had 5 sons and 1 daughter between 1820 - 1830. Three of the sons were Julius Nikolaus Franz Guggenheim (my Gt.Grandfather), Moritz and Gustav and their daughter was Amalie. Joseph died abt.1829.
I believe his wife and some of his children moved and were resident in Vienna, Austria, sometime after his death.
I have much Info. regarding son Julius, a little on daughter Amalie, but none on the four other brothers. More Info will be very much appreciated. Regards, John Titcombe
