Hope we get some kind of progress on this one. If Tinda was 103 when she died in 1975, then she would be born in 1872. I have had her birth year down as 1882 up to this point. Give or take 10 years and see what happens if he can't find her records from 1975. That's why the tombstones are big help when it comes to knowing when they were born and when they died. Do you know where she's buried?
1870-1880 area in Honduras, would the regions bordering Guatemala be where Christina's family comes from? I learned that in 1870, the Mayans invaded Corozal and occupied there. That's during about the time Christina would be born.
