I added the mother to Louis Lussier-849 which did not have the mother linked, so now all siblings are showing as full siblings.
I also proposed a merge with Louis L'hussier-19 which is obviously the same person, just different spelling. Unfortunately, there are no sources on Lussier-849 and the sources on the other one do not show what name is on the Baptism source. Since Lussier is listed as an Other Last name, that name should probably be the LNAB and the merge should be done into that profile.
I have proposed a merge of the spouse profiles also. Merge should be done into the one that has the parents .
