I've recently gotten a copy of my husband's genealogy from my FIL and have one lonely little ACHA in the tree... She does not appear to be related to yours, Toby, but if you (or anyone!) ever find a connection, I'd love to hear from you.
Cleofe (sp?) ACHA married Stanislao COCA-ESCALERA.Both Cleofe and Stanislao were born, married, died and were buried in Cochabamba, Bolivia.Based on my info, they had 6 children, many or all of whom may still be alive - based on one half-sister whose DOB I do have, they would probably be in their 80's or thereabout.
Any info would be appreciated!Replies in Spanish will take me a little time, but I've got an interpreter.:-)
