I think we must be related...and I'm hoping you might have additional information.
I think your Nestora Ramirez must be the (half-)sister of my GGGG Grandfather Jose Miguel Tomas Ramirez. Here's what I know (see below)...as you can see I have that his father was Antonio Ramirez but that his mother was Maria Encarnacion Canales; that they were married Feb 13, 1826 in Mier. I'd like to know if you have more info on Antonio Ramirez...something you can email me.
