Well. I am apparently a direct female-line descendant of this woman:

As are over 140,000 people in the United States.
I also discovered that the pedigree collapses at her, as the descendents of her two husbands, Jaques Hertel and Francois Morel, ended up marrying each other.
She'd probably be irritated to learn that most of her descendants don't speak French.
