Trying to find the parents of Petronila de Retamosa Macias Valades Gonzalez de Gardea

I have been trying to figure out who the parents of Petronila de Retamosa Macias Valades Gonzalez de Gardea are and still have no real clue. Petronila was married to Joseph Lozano in Teocaltiche 23 February 1666. All other information on her comes from baptism, marriage, info mat., wills, and burials of her children in Aguascalientes. In each record she is listed with a different combination of surnames.

Considering Petronila’s Mestiza/Tresalba status, I am under the impression that she may be a natural daughter of an Espanol father just as her mestizo husband Joseph Lozano was.

Her use of Gonzalez and Gardea hint that she may be descended from Martin Perez de Gardea and his wife Mariana Gonzalez de Ruvalcaba in some way but I am not certain of this. Her use of Macias and Retamosa suggest that she must be descended from Nicolas Macias Valades and his wife Leonor Retamosa in some way. But how?

I thought I was close with the couple Francisco Martel and Ana Macias. Both are descended from Nicolas Macias Valades and Leonor de Retamosa. Ana Macias mentioned having a daughter named Petronila in her 1698 will. Only this Petronila would be too young to be the same Petronila married to Joseph Lozano.

I have been noting the Padrinos and Testigos of Petronila’s children who share surnames with hers for clues.

*A Beatriz Gonzalez is Padrina to the baptism of Petronila’s son Juan Lozano 21 August 1679.

*A Phelipe Gonzalez is a testigo to the marriage of Petronila’s son Juan Antonio Lozano 28 December 1710. Phelipe Gonzalez gives his age as 46 setting his birth at about 1664.

*A Pedro Macias is a testigo to the marriage of Petronila’s son Eugenio Lozano, about 15 January 1697, and to the marriage of Petronila’s daughter Juana who married Sebastian de Ulloa 25 May 1696. Pedro Macias gives his age as 37 or 40 setting his birth at about 1660 or 1656.

*A Joseph Macias Valades is mentioned in the burial record of Petronila’s daughter Juana 20 November 1738.

*A Miguel Martel (perhaps a relation of the Francisco Martel mentioned above) is a testigo to the first marriage of Petronila’s son Manuel Lozano 10 February 1698. Miguel Martel gives his age as 47 setting his birth at about 1651.

*An Antonio Macias Valades is a Testigo to the marriage of Petronila’s son Joseph Lozano 12 August 1716. Antonio Macias Valades gives his age as 40 setting his birth at about 1676.

*Joseph Lozano married Maria Teresa Nunez 12 August 1716. Maria Teresa Nunez is the daughter of Juan Nunez and Teresa Macias Valades. Teresa Macias Valades is the daughter of Gabriel de Castaneda and Maria Valades.

Does anyone know how these Padrinos and Testigos fit in with the descendants of Martin Perez de Gardea and Mariana Gonzalez de Ruvalcaba or Nicolas Macias Valades and Leonor de Retamosa? Has anyone seen Petronila or her children listed as Padrinos or Testigos of their lines? This may help give clues to who her closer relations are, and may help narrow down potential candidates for her parents – or paternity if she is a natural daughter.
