Juan - I am seeing yr post here about your NM Pena line. I am testing a guy from AZ to see if his Pena Ydna matches that of my husband and his father John Pena - a TX/MX line. We are a match with a man (now deceased) in CA whose TX/MX line shares our Ydna. We are also a match with another man's Pena Ydna who has no ancestors or fam tree listed on FTdna and who does not respond to my emls - which is common for FTdna. But I hope you will Ydna test and establish whether your Ydna is the same as the TX/MX Pena Ydna.
Please contact me at bettepena AT hotmail. com if you get this message. I am currently testing a double Pena who is both TX/MX and NM (NM on his mother's side) whose line sounds like yours as far as it has been found to go. We'd like to work with you should you decide to do the test.
Kind Regards - Bette Pena
