MY grandfather was Leon (Leo, Lionel, Leonel, etc) from Tampico MX area.He married Petra Nava approx. 1925/1927He died approx. 1929 when my father (Odon) was an infant.For so many years we've all wondered whatever happened to his family? Did he have siblings? etc? My dad is going on 80 along with his twin brother.It would be great to find out more about his dad's side of the family.
