Hi, I just completed a bunch of merges in the Daniel LeBlanc line. You were given good advice when trying to add Acadians before the 1800s. Most of them are already here but names may vary. Here is how the Acadian Project prefers to handle names: https://www.wikitree.com/wiki/Help:Familles_Acadiennes
. We use the surname spelling that the Acadian historian Stephen A. White uses. Put alternate spellings in the "other last name" field. Good luck and please contact me or Roland Arsenault if you have any questions.
But, if you have additional information that is sourced!!!! (I can not emphasize this enough), please add it directly to the profile following the style that is already there (or improving what's there as the case may be). Add the sources in detail so they can be verified by others.
Thanks for contributing to the Acadian Project and please join us if you are so inclined. https://www.wikitree.com/wiki/Project:Acadians
