I am not researching these people, just entering information from one of my books, "Randolph County, Indiana, 1818-1990."
"Edward G. Adams, was b. in Monro Co., OH, Aug. 4, 1840 to John Q. and Patience (Garretson) Adams.John and Patience were m. Oct. 5, 1838 in Sunbury, OH.John was the son of Thomas and Lydia Adams of Monroe Co., OH.Patience was the daughter of John and Henrietta Garretson, also of Monroe Co., OH.They were all of the Quaker faith."
"When they moved to Randolph Co. is not known, but Edward joined the Cavalry and was a private in Co. C 39th Reg. of Indiana volunteers.he joined Aug. 11, 1861 and was discharged on Nov. 4, 1862, the reason for discharge was organic disease of the heart.He did serve at Shiloh and Nashville, TN.Edward was 20 years old when he joined the Army."
"After his discharge Edward was a farmer in Randolph Co.He m. Nancy Clevenger on Dec. 4., 1865 in Winchester, IN.The parents of Nancy have never been proven."
It is stated in Hinshaws books that her parents were John and Nancy Clevenger.There is further information on the children of Edward and Nancy.There is a photograph of Edward Adams as a young man, not in uniform.
I don't know if there is a relationship, but there were Clevengers in the eastern panhandle of what is now West Virginia.
