I’m also a descendant of Louis A Latil. Achille A Latil> Julius A Joseph Latil > Emma Eulalie Latil LaGroue.. I have heard stories about the gun invention. I would love to see any articles that you have. Like you I love family history. Also, living in Louisiana, I plan to visit the Houmas House soon. The Old French house in the back is part of the Latil history.
