I have discovered at least two individuals with bertrand dna that I also have a dna relationship to

That is potentially very significant, especially given the Pierre LaGasse + Jeanne Bertrand connection we are investigating.

If you have DNA relationships to two different people who have documented Bertrand ancestry, that can provide an independent genetic clue supporting a Bertrand branch in your ancestry. But there is an important distinction:

DNA can support the existence of a Bertrand connection; it generally cannot, by itself, prove that your Jeanne Bertrand was the specific ancestor.

Why this is interesting for your Lagasse research

We currently have this proposed line:

Martin LaGasse

↓

Michel LaGasse + Laurance DeVimeur

↓

Pierre LaGasse + Jeanne Bertrand

↓

Ludovicus Lagasse, 18 June 1705

If your two DNA matches both descend from different Bertrand families/branches, we should investigate whether their documented pedigrees converge on:

• the same Bertrand ancestor
• the same geographic area as Jeanne
• Aisne / Picardy / Hauts-de-France
• Alsace/Wissembourg
• or another location associated with your Lagasse line.

The two matches could be especially useful if you have these details
