Congratulations Manny,

I have spent many hours looking for this info and never confirmed it. I suspected but had no luck. I was right in identifying his father but never could confirm it because I thought he was from the first marriage.
I thought I was wrong and you were right when I first read your email but a couple of hours later as I was taking a shower I thought about why I had originally placed him with the first wife and came up the idea that this was another time where a dispensation incorrectly places the second wife as the mother. Many years ago I had an ancestor who was incorrectly placed by many genealogist because of faulty record. When she married her stepfather was listed as her father. Her father had died when she was young and had left another child also. It was clear that after going over all the available data that she was the biological daughter of the first husband, a Martin dell Campo, and not of her mothers second husband who had raised her. Many genealogist

Hi Manny

I just found out that the Martinez de Alarcon family sometimes used a different variation of the name and that many were known as Ruiz de Alarcon. Hopefully this information can help us go further back on the Miguel Martinez Alarcon and Josefa Bautista de Rubalcava line.

From a couple of descriptions I found of a possible relative of Miguel Martinez de Alarcon :

"Juan Ruiz de Alarcon y Mendoza (1581-1639). Mexico. Nacio en Mexico y vivio gran parte de su vida en Espana. Era hijo de Pedro Ruiz de Alarcon y Leonor de Mendoza, ambos con antepasados de la nobleza. Estudio abogacia en la Real y Pontificia Universidad de la Ciudad de Mexico y a comienzos del siglo xvii viajo a Espana donde obtuvo el titulo de bachiller de canones en la Universidad de Salamanca. Ejercio como abogado en Sevilla (1606) y regreso a Mexico a terminar sus estudios de leyes en 1608. En 1614 volvio otra vez a Espana y trabajo como relator del Consejo de Indias. Era deforme (jorobado de pecho y espalda)
