Justin Swanström@Justin is the curator for this profile. Tagging him in case he's not seen this discussion thread in the hope that he may be able to help you better than me Brittany. I would like to point out while here that on Geni it won't be so much the case of you adding Marie-Jeanne Lejeune, Miq'Maq but rather of finding where your tree overlaps with this tree and merging it in as we are trying to create one single shared world tree.
Brittany, I'm sorry I can't help you directly. I took over as curator of this profile when another curator resigned and was worried that it (and others) would be de-mastered. The curators had a spirited debate about whether it might be better to let the profiles be de-mastered. Perhaps it would have been. We're still looking for a curator who wants to take over the French-Canadians and Metis.
I suggest you send a message to the other profile managers to see if any of them can cite any sources. In the meantime, I'm happy to make any changes you need, if they are supported by primary sources.
