While I cannot offer much help, I thought it might be useful to let you know that I am working on a book about the French in New Mexico. I have come upon the Talons while researching the La Salle expedition story, as two of its members, Grolet and L’Archeveque, ended up in New Mexico where they founded family dynasties. You can see more at www.newmexicofrenchhistory.com
You probably know about this; I met some time ago Betsy Francois, whose novel “Blunders of the Patriarch”, covers five years in the lives of the Talon children. She lives in Socorro, New Mexico. She had a website, www.betsyfrancois.com, but it does not seem to work any longer.
If I come across anything else regarding the Talons, I’ll let you know.
How is your book progressing?
All the best, François-Marie Patorni firstname.lastname@example.org
