Hi

For those of you researching any links between the surnames in the subject line, I found this baptism in the records from

Sagrario, Leon, Guanajuato:

15 sept 1646

Maria, dau of Nicolas Villalpando and Maria de Vielma

Padrinos: Francisco Xaen and Ynes Arias (his wife)

I came across it because I am looking for any link between the surnames Olar, Villalpando, and Aguila.

In Asientos, there is an Antonio de Aguila married to a Juana Olar, and I want to find out if Antonio has his roots in Leon.

The surname Olaes shows up in some records mentioned here in NR . Does anyone know if Olar is an alternate spelling of Olaes?
