Hello Emilie,

I don't know if I can be much help with the Olague surname but I will 
give you what information I have. I have two Olague lines that I found 
just this year. One is when I found my ancestors Pedro Chavez Banuelos 
married to Aguada Olague in 1681 whos parents are Miguel Olague and 
Juana De La Torre Del Rio. The other line is Sebastiana Olague married 
to Francisco Davila Caldera in 1713 no parents for her because she was 
married before to a Nicolas Dena. But I did find a despensa in the 
Sagrada Mitra book that says Sebastiana was the hija natural of Jorge 
Olague doesn't give her mothers name. 
Thank you and all the group for your warm welcome. Since I came upon 
this site it has been so enjoyable reading all those messages. 

Regards
Sally
