I have now found out that my Dorothy Seybold's maiden name was Murdock. Her parents were Sheldon and Melvina Murdock who lived on Martindale in Detroit, Michigan at one time.
Sheldon Murdock is my Dad's Uncle - his Mother's brother.
I have much info on the Murdock family now if anyone is interested.
I know Dorothy had 2 sons and a daughter; The sons were roger Jr and Eric. The daughter Robin.
Does anyone have contact with the above names?
