Here is what I do know:
I do know all about this generation since my dad and grandmother are
still living.
I know that Andrew Mann was married twice (Mary Williams and
Angieronia) and those marriages produced 6 children (3 girls and 3
boys). I know all of thier names and personally knew all of my great
uncles (Seaton, Newton and my grandfther Silas). I know about the girls
as well and their marriages (Nora, Dora & Cora).
The next Silas Mann was married to Marriette and they had 5 children
(Andrew, Clauinda, Elizabeth, James & Marshall).
All that I know for the next Silas is that he was married to Polly.
Richard Mann was married to Lucy and had 4 children (Silas, Stephen,
Martin & Daniel).
John Mann died in 1789
