William Elbert Riddle was my grandfather and he never lived in the Mckinney area that I am aware of. He did have a cousin that lived there. My grandfather was born in Mexia, Texas and raised his family in Groesbeck, Texas. When my father was 10 years old, he, my grandmother (Cathrine Lee Vickery born 1889) and his sister, Chloe Dell Riddle, left Groesbeck and moved to Dallas, Texas where my grandparents got divorced.
My grandmother was known as Katie to most people. She had 5 children that grew to adulthood, 2 that died young and 2 unnamed still births.
I cannot remember all the names, but I'll try. My son, William Daniel has all my family history now. I no longer collect the information.
Eley Ray died in infancy
Mattie died age 8
