Hello, Moises – it has been some time since I last messaged you on this ancestor. My dad did the Big Y test and matched up to a another male from the San Juana Rodriguez y Quintanilla children. So good news, we have matching DNA to establish Juan as a common ancestor for one male line for each of Juan’s wives. Bad news is that I keep running into a wall in terms of connecting with descendants of Juan’s Siblings: Antonio, Zenon, Presciliano, and Luciano. Further, I know there were multiple marriages to Flores females who descended from Marcos Flores (Porcion’s 38, 39 and 40). Juan’s first wife MGVela was from the Marcos Flores line as an example. Juan’s mother, Maria Guadalupe Vela was a descendant and Juan’s grandmother Maria Gertrudis Flores was as well. Anyway, I have tried to work through the South Texas DNA study but it’s been a challenge. If you want to catch up further ont his topic, let me know. It has been a real journey trying to find these ancestors.
