I noticed on the side bar several videos for a Leo Monosson,a singer and actor. Leo, born Leon in 1897, is the son of Isai Monosson and Malvina Szereszewki. For comparison my grandfather David was born in 1887,his brother Fred in 1892. A collection of the videos can be found on YouTube
Since I haven't been active in my genealogy research I corresponded with Michael to find out more information and he sent a descendant chart. Seems that I met his second wife Stephanie in Florida,another story, and his daughter Vera Monosson Steinfeld here in Tel Aviv and corresponded with her about the possible connection. So far we haven't been able to find the "link" both Michael and I both think that Leo's grandfather Leon,born beteeen 1835-1845 and our Gr-grandfather Abraham/Adolphe, born around 1847 were either siblings or cousins. Isai was a in the diamond business and sold stones to the famous Faberge. The families had close ties and Monosson is his private telephone directory. This fact we found out from a bit of professional research we did.
Michael sent me some images of Leo that he bought on Ebay a few years ago. Here is the sideshow.
