Wow, so nice of you to reply to my query. Robert's father was Floyd Pardon LYON, s/o Frank Pierce Lyon and Laura (WALKER) Lyon. Floyd was also a brother to my two oldest children's paternal grandfather, Claude Ray Lyon. I was married one of his many grandsons.
I'm in the process of putting together years of research and photos of the LYON family history along with most of the immediate branches (siblings' families, etc.).
I would love to communicate with you regarding Robert's family. If you're interested, please feel free to contact me at my personal email - ptownpest at aol.com
Hope to hear from you soon!
