Stevenson/Stephenson/Stinson/Evans/Prather/and assoc.familie

My family is the Stevenson family who came from Maryland.My John Stevenson married Mary Ellen "Polly" Prather in Mason Co., Ky.Also Reginald Prather who married Rachel Ross were the parents of Mary Ellen "Polly" Prather. Mary Ellen and John Stevenson were married in Mason Co., KY., in 1802. I am looking for parents and siblings of John Stevenson from Maryland. Know he is descended from Edward and Mary Stevenson from Baltimore Co., MD., but don't know which of Edward and Mary's children he was descended from. I am also looking for parents and siblings of Rachel Ross who married Reginald Prather. They were as far as I have been able to determined, married in Washington Co., MD. This is not set in cement. I know that 3 of the Stevenson men, besides John went to Mason Co., who were brothers, am hoping someone knows if they were brothers to John also.The brothers who I am sure of are:Thomas who married Mary Evans, daughter of Job Evans of Baltimore, MD.Nathan who married Sarah Evans, also daughter of Job Evans of Baltimore, MD.Richard who married Ursula Wood.These men were sons of Edward, of Richard King Stevenson,of Edward and Mary Stevenson of Baltimore.If any one has info to show any other children, would appreciate any help. I will be happy to share any info I have.Big1Gran@aol.com or Spiritgrny@aol.com
