Hello there: To tell you the truth, I don't have alot of info., but I will look into what I do have listed and see what I can find.the Ma you mentioned, yes usually does mean Maria.My grandmother and her sisters on census info. has them either listed as M. followed by their name, or Ma. then their name, and it stands for Maria.There was an awful lot of that.The majority of my Aguilar's are listed as De Jesus Aguilar., so who maybe. My grandfather I did find out, his brother was NOT Damian Aguilar.Damian's father Manuel was my grandfather Pete's (Pedro) brother. My grandfather's parents were Antonio Aguilar and Lionora Garcia.Antonio was the one that supposedly was NOT an Aguilar, but we can't prove that... He claimed to be a Stong, but only Heaven knows the truth.Too many stories floating around. I will email you, but I don't know if you will be able to pick it up.Alot of people cannot, as I am on webtv.Let me know, I won't be able to write before Monday probably, but I will promise to write.Don't know if I have anything you can dig into tho'. Hope so.
