The dates I have for MIguel Chavana and Maria Catarina de Leon are from the FamilySearch link of the Church of Latter Day Saints, i.e. the Mormons.
The Mormon timeline fits in better with that section of my family tree. THe reason for this is because their descendants are well documented.
I am a descendant of the famous 'de la Fuente' aka 'Fuentes' family from Castanos. I have lived in Toronto all my life, but I was born in Monclova, Coahuila, b.1969. My Mother is Maria del Rosario Lapeyre Blackaller b.1939. Her mother was Emma Blackaller Fuentes b.1911. Her Mother was Catalina Fuentes Saenz b.1881. Her Father was Pedro Cruz Fuentes Elizondo b.1861. His father was Anastacio de la Fuente de Hoyos b.1819. His mother was Maria Catarina de Hoyos Chavana b.1796. Her mother was Josefa Gertrudis Chavana de Leon b.1772. And finally her parents were Miguel Chavana b.1748 and Maria Catarina de Leon b.1753.
I would like to clarify which are the accurate dates. I know for sure the 'de la Fuente' dates. I know for sure that Jose Manuel de la Fuente Flores b.1792 married in 1815 Maria Catarina de Hoyos Chavana b.1796. ANd I know that Josefa Gertrudis Chavana b. 1772 was her mother.
Looking forward to resolving this section of history. I will not enter your data regarding the parents of Miguel until further notice. By the way do you know who Maria Catarina de Leon's parentes were?
