The only Indian there might be is if the Piper has any. Not in any of the other family lines that you mention, in my opinion. In the pictures of the Scallans in my husband's family, they do look very dark and have black hair, but I guess that is a combination of the Irish and French.
Some points of interest:
The two wives of Zenon Bauthier - Clementine Riche and Deville - were sister, I think. Also, married to Germain Riche was Carmelite Lemoine; married to Elphedge Riche was Elena Lemoine and married to Celestin Gauthier was Arthemise Lemoine - Again, I think all sisters.
I got my Scallan file from a friend online. I do believe it is well-researched but does not include the sources per item. It came just with a list of sources.
I'll be happy to share whatever I have, and would love to get details and sources from you to add to my file.
You can contact me personally if you like.
