Saul Mendelssohn (1735 Dessau-1805 ?) was the brother of the famous
philosoph Moses (1729-1786).
I am looking for documented datas on his life, on his wife and on his
children : datas which I didn't find in "The Unbroken Chain" (Neil
Rosenstein) or in the answers of several Jewishgenners who kindly replied
to my questions about Mendelssohn's genealogy.
I only know that he had a grandson (or posthume son... not very probable
at the age of 70 !!) named Saul,born in 1805, who died in Poland.
What happened between 1755 and 1805?
Where could I look for information?
Thanks in advance
