Gary,I too am a 5th generation descendant of William Riley. Albert Kimbrell whom you visited was my godfather. My grandfather was John (juan) Kimbrell and my greatgrandfather was sherrif George Kimbrell. My brother-in-law Pablo Montoya and I provided information on the New Mexico Kimbrells to Sonya Smith and others. I have photos of George's children- Beatrice, Juan, Bonifacio and William. If you are interested I would like to exchange photos.
