Updating the LEBEGUE - THOMAS family

It's been almost 3 years since we've updated this branch of the tree. I found a mailing list today on Cousins77 with a few names similar to ours : THOMAS, LEBEGUE, DABON.

They were all researched by M. Jean COUSIN. I emailed him, and only a couple of hours later I got an email with extra information (3 generations and part confirmation of my hypothesis...).

I'm now stuck with a person : on the grave there are 3 persons I can't identify:
* Marguertie REMY, died after 6 days in 1895. Who's she the daughter of ? Definitely her mother must be a THOMAS ?
* Sophie MANCELLE, spouse DABON (and not widow), died at 64 in 1889 (meaning she was born in 1825). Who's she maried to ? M. Cousin sent me a "Marie Anne Sophie MANCEL 1776-1826). Very close, but at least one generation apart.
* Edmond THOMAS, died at 14 in 1851. My guess is that he is the brother of Adolphine THOMAS.

I think I need to go to the AD 77 again...

In the meantime, on Geneanet and on patro.com, I found many folks relating to the DABON in Moret-sur-Loing. 2 other branches too in Hericy and Montereau (close by). Looking for a link there as well.
