it was very exciting to see your posting.
I'm decended from John R. Shepley too.
His daughter, Mary Louise Shepley married Isaac H. Lionberger.
You must be from one of his other daughters, Margaret, Anne or Mary.
I come from the 2nd daughter, Louise Marion Lionberger ("Gaga") ;
Her daughter, Violet, had a daughter, Joan, who is my mum.
Perhaps we've even met at the J.R.Shepley family property in Marion, MA?!
I'd be happy to share my research with you.
