Ignacio Martinez or Martin de Sotomayor

Hi All, Im looking for the parents of Ignacio Martinez de Sotomayor
who married Petronila de Magana (bapt, 1 Nov 1698) on 30 Nov 1725
in Jalostotitlan, Jalisco. I have a suspicion that Ignacio was son of
Isidro Martin de Sotomayor and Josepha Lopez de la Cerda.

Regards,
Daniel
