I would love to have a copy of the family tree you mentioned that is in the book "Natchitoches:The Up-To-Date Oldest Town in Louisiana". I checked the Birmingham Alabama Library's online catalog, and we don't have that one.
My ancestor, Joachin de Ortega y Prieto, married Marie Damasainte of the De Soto-St. Denys clan in Louisiana. I knew nothing about our DeSoto-St. Denys relatives until I started researching my Morein/Ortego family. My paternal grandmother was Marie Adiede Ortego, d/o Jean Baptiste Ortego and Louisa LaHaye.
Winston De Ville, F.A.S.G., well-known historian and genealogist wrote a nice piece for "La Voix des Prairies" (No. 10) on my ancestor "Joachin de Ortega y Prieto: The Spanish Ancestry of a Gateway Pioneer in Colonial Louisiana". I found a copy in the Evangeline Parish Library in Ville Platte.
My dad spoke of other ancestors, but for some reason, never mentioned DeSoto-St. Denys. I was thrilled to find a picture of my 2nd greatgrandfather, Pierre Felix Morin, who was born in 1819 in Pointe-a-Pitre, Quadeloupe. I asked my cousin who now has the picture how she happened to have it. She said her dad wanted the picture and simply took it from his father's house. When I asked about other pictures, she said the house from which Pierre Felix's picture came burned and all it's contents burned wit it!
