Hi Nora,
My dad is an Ybanez and he was raised in Tilden, he as lots of brothers and sisters. Giving us lots of cousins, some we've never met.
I know his father's name was Peter (Pedro) Ybanez. We don't know much about his family's history due to his father being adopted or taken in by a Shiner. According to stories, my great grandmother was of Indian descent and the mid-wife there in Tilden during the late 1800's. I've heard my dad mention the last name Heritage but not sure if he was talking about neighbors or cousins.
Let me know if you'd like more information, by email
mywil1@yahoo.com and I'll ask my dad.
