I would not move farther forward into Ludovicus's descendants yet.
First, we should solve this:
Who exactly was Pierre LaGasse (~1674), and can we prove he was the son of Michel LaGasse and Laurance DeVimeur?
Once that is established, we have a defensible line:
Martin LaGasse → Michel LaGasse → Pierre LaGasse → Ludovicus Lagasse
Then we can trace Ludovicus's own children and grandchildren with much greater confidence.
If you upload the Filae page as a screenshot, especially the section showing Pierre's parents, spouse, children, sources, or events, I can compare it against the parish-record evidence and tell you which parts of your tree are actually supported by records and which are merely inherited from an online tree.
