I am the the great granddaughter of William Jenkins Hayden and Rose Hayden (Rose Jeanette Morgan) of Chaptico, Maryland. My grandfather was Raymond S. Hayden Sr. (deceased 8/06/1966) who was "Margurite's" brother. My father was Raymond S.Hayden, Jr.(born 9/12/1938 in Mechanicsville, Md and is deceased) . It is my understanding that due to being parceled out to relatives, none of these siblings kept in contact.
I have verified the names that are mentioned and have asked my Aunt, but she has no idea where they are, what if any their married name is/would be or even if they are still living.
Good luck on your search.
