Search for Bondy and Lederer

Hello,
Recently, I discovered a link with family Bondy and my family Lederer. The only thing I know is that 2 brothers Bondy got married with 2 sisters Lederer (between 1840 and 1860). They add a factory of cigars called "Bondy & Lederer". I would be very interested to have informations about them and their descendants.
Thanks a lot
