Delores, I knew Eva Buckles and Hardeway Harrison in Kansas City, Kansas, and their daughter. I'm not sure, the daughter may have been named Arlene. Also I knew Hardeway's sister Annie, her husband and their son, Dale.
All of this took place when I was a child, and I don't remember it all too well, but whenever we had a family get to gether they all came. Hardeway and Eva lived near Riverview Street in Kansas City, Kansas.
I remember Mom and Dad speaking of R. C., but do not have a clear picture of him in my mind.
Most important, though, is that they are descended from the same family as I am. I will share all of that with you if you do not already have it.
Your query is an old one--2006, and probably you already have all of the info.
I'll look for more information.
