Hi, Deb. I am a Huffstutler, too. I don't know anything about Claude's siblings, but I am related to Claude. Here's my story:
My father is Dean Huffstutler. His parents are Ira and Susan Katherine (Marquis) Huffstutler.
Claude's father and Ira's fathers were brothers, so your grandpa and mine were cousins.
I also have another connection in that Lilly was my Great-Grandmother's (Hannah Pinnel Marquis)cousin.
My dad and his sister, Helen visited your mother (who he says goes by Marie) about six years ago and visited the family gravesites at Mt. Nebo. We live in Elgin, IL--about 40 miles northwest of Chicago.
My Aunt Helen Huffstutler Ferreira knows the most about our family lineage and has done some extensive research about it. I will pass on your web page information to her. She's not computer adept.
It's nice to meet another relative, even if it is online. :)
