My husband has a Dominguez connection, very early. Maria Ignacia Dominguez, b. Abt. 1732, Sinaloa, MEX d.Jul 1830, CA who married Antonio Buelna, b.Abt. 1728, Sinaloa, MEX.
We have no further information on Maria Ignacia. Are there any DOMINGUEZ researchers out there who may shed light on this family?
