PS. my branch is on Eusèbe side of the family which traces to my mother (her mother was an Arsenault).
I also have some data on Allain`s as my mother`s father was an Allain. Unfortunately, nothing on Abraham Allain however. (if you want to start at the root Louis going down, I have all of that lineage)
If you need more data, don`t hesitate to contact me.
