Paul Aviles, who is a descendant of Francisco X. Martinez through his first wife, Rafaela Serrano y Ruiz, has created an online genealogical tree showing ancestry and descendants of Dr Francisco Martinez Aguirre. Note that the default language is Spanish but you can change it to English using a small selector in the upper right hand corner of the page:
Genealogical Tree (this will open in a new browser window)
The tree shows ancestors of Dr. Martinez back to the early 1600’s. It has been created using very specialized genealogical software which makes it possible to navigate through the generations by clicking on various links and tabs. It takes trial-and-error to get used to it but it is well worth the effort and very informative.
For the family of the second wife of Dr. Martinez there is a single special page here on the fxmartinez.net site: The Del Pozo Family Genealogy.
