I was wondering if there was a connection between Ruybal and Ruybalid. Ruybalid was originally Ulibarri but was changed when the Ulibarri migrated to the San Luis Valley of Colorado. My husband's mother maiden name was Ruybal and they came from the same valley. My maiden name is Ulibarri.
I have since found my mother in laws grandfather Simon Ruybal as Simon Roybal.
