I attached Jose Arcadio Argüelles baptism registry and it’s a very interesting one, since he and his cousin Ambrocio were baptized at the same time I guess, the two records are consecutive, but also very interesting is that Arcadio’s godparents were Roman de los Santos Coy and Guadalupe Arguelles, while Jose´s godparents were Joaquín Argüelles and Francisca de los Santos Coy.
Also good it mentions all grandparents, even I think Arcadio´s got mixed.
