FRANCISCO CARRILLO aka DIEGO CARRILLO in Sierra de Pinos: CARRILLO DE SANDI?

Hola primos y primas,

My g6's are Francisco Carrillo and Maria Guadalupe Diaz de Leon, residents on Real de San Nicolas de los Angeles, in Pinos (and at times, in Asientos Ags). He also went by "Diego Carrillo," so I'm going to refer to him as "Francisco Diego Carrillo," to avoid confusion. They married 10 Aug 1728, Limpia Concepcion, Cienega de Mata, Ojuelos, Jal. According to their partida, they did their IM in both Cienega de Mata and in San Matias, Pinos, but I've been unable to find either: https://familysearch.org/ark:/61903/3:1:9392-2G9D-N8?wc=3J6H-SP8

I've established that Maria Guadalupe Diaz was daughter of Joseph Diaz de Leon and Antonia Delgadillo, of Encinillas (see http://www.nuestrosranchos.com/en/node/20091), but I'm still brickwalled on Francisco Diego Carrillo. I thought I might present what I have on him, to see if any of you might be able to help me shake a brick or two loose. This is relevant to descendants of Andres Diaz de Leon-Duron and Maria Gertrudis Estefana Carrillo-Diaz, many of whose children would populate Montesa, Zacatecas.

Francisco Diego Carrillo was testigo on the 06 Feb 1723 IM for Cristobal Marquez and Maria Simona, in Pinos. Unfortunately, his age isn't given, nor does he sign his name. He says he had known the pretenso for about 10 years, who was originally from Aguascalientes. Incidentally, the next testigo on this IM is Francisco Xavier Carrillo, who I believe is the same who married Maria Candelaria de Rosas, residents on Salitre. The 2 Francisco's would cross paths, over the years, being padrinos for each other's children. Likely cousins, maybe even brothers:

When a testigo on the 26 Apr 1743 IM for Joseph Cayetano Diaz and Maria Quiteria Carrillo (daughter of Francisco Xavier Carrillo and Maria Candelaria), Francisco Diego Carrillo gives his age as 53 (b. 1690), and is given the name "Francisco CARRILLO BISAIS." He could not sign his name, so I'm unable to verify the second surname: https://familysearch.org/ark:/61903/3:1:939N-B9WJ-Q?wc=3P91-SP8

When a testigo on the 27 Oct 1743 IM for Francisco Xavier de Lira and Juana Maria Quintanilla, Francisco Diego Carrillo is listed as "Francisco CARRILLO DE YSAIZ." He again gave his age as 53, and said he was originally from Teocaltiche, and had been living on Angeles for 30 years (ca 1713). Now we know where he was from, and when he moved to Angeles:

By the way, the Notary in Pinos in 1743 was Andres Hilario de Baena (beautiful penmenship; detailed info, including occupation and spouses of some testigos), who did both of these IMs. We know scribes used phonetics, when transcribing, so this tells us that, either Andres Hilario was partially deaf, or, Francisco Diego Carrillo annunciated his name, very poorly! "Bisais"? Or "de Ysaiz"? "Bisais" is French, but could be "Vizaez" and variants of, though I think it's likely "de Isaiz," "de Isaias" or "de Isassi," all which I've seen, during my research in Los Altos (there HAS to be a Carrillo-Isassi union in this timeline, somewhere... anyone?).

In marriage records for their children, I've seen them listed with the surnames "CARRILLO LIZANDI" and "CARRILLO Y SANDI," which is obviously "Carrillo de Sandi" (could "Bisais: and "Ysaiz" be corruptions of "de Sandi,"??).

Checking the baptism records, 1680-1695, in Teocaltiche, for "Francisco" or "Diego Carrillo," I have 2 candidates:

Diego (Español), son of Geronimo Carrillo and Maria Delgadillo (Lozano-Sandoval?), b. 17 Jun 1688. I believe Geronimo Carrillo was son of Diego Carrillo de Sandi and Maria Lopez de Rubalcava, which would give us "Sandi": https://familysearch.org/ark:/61903/1:1:J93R-NYK

Francisco (Mestizo), son of Francisco Carrillo and Elena Diaz, b. 29 Jul 1687. Francisco Carrillo and Elena Diaz, who appear in the 1681 Teocaltiche Padron, were Mestizos, whereas Francisco Diego Carrillo is always "Español." I've seen several individuals, born Mestizo but categorized as Español, later in life, so I take that with a grain of salt. One thing leading me in their direction, is the fact that Francisco Diego Carrillo and Maria Guadalupe Diaz had a daughter named "Elena Josepha Carrillo," who could've been named for Elena Diaz - though, I've seen "Sandi" appearing in no record related to this family group: https://familysearch.org/ark:/61903/1:1:NYHM-BV1

While searching archives in the Sagrario, Leon, Gto, the 12 Feb 1691 marriage of Joseph Carrillo and Juana Morales Prieto caught my eye: he was son of Joseph Carrillo Altamirano and Catalina de Lira Ysaias. I haven't been able to do much research on this family group, but "Carrillo" and "Ysaias" together is too uncanny, and the timeline would correspond. Does anybody have anything on this couple?:

Thanks for any assistance!
