I believe Riley Willoughby's wife is Sarah Elizabeth Thomas, my grandmother's sister. Rileys full name was william Riley Willoughby. Sarah's sister Harriett ellen Thomas married a Herman Melvin willoughby, but I'm not sure if there is a connection to the two Willoughby's yet. I have extensive information on The Thomas line on my tree. I am tring to confim that Henry c. Thomas & Martha Jane Brown are the parents of this Sarah Elizabeth Thomas.
I have also seen Riley spelled as Raleigh.
