WOW! Sounds like you've done some homework. Like you, I'm just getting back into genealogy after a three year layoff. Is there anything we can share with one another, in hopes of filling out our prospective family trees?
Is there a "Pacheco Family Tree" out there that I've not stumbled across? If the name goes back to Spain, someone has had to publish something tying in my family line from Mexico.
I look forward to assisting you in anyway I can.
