These look like two different Rene Rimbaults to me, and should NOT be merged. According to Stephen White's DGFA, p.1397-1398, Rene Rimbault-7 and Anne-Marie Unknown-182545 are the parents for this family, but there should only be 7 children, not 10. Children Anne, Rene, and Madeleine/Magdelaine are duplicated and a decision needs to be made to either disconnect the extras or merge them...probably merge but I haven't looked at them closely enough to say for sure.
Rene Rimbault-27 appears to be a completely different person. Neither he nor his daughter Marguerite Madeleine Rimbault-26 appear to have ever been Acadians. Looks to me like a case of mistaken identity. She should be disconnected from Anne-Marie Unknown-182545 and left without a mother until someone else comes along with time to work on the family.
I can provide info from White's DGFA if needed to help clean up this family.
