The "Adkins VA" you mentioned is Atkins with a "t" and is located a few miles east of Marion in Smyth County, Virginia. I found a marriage record in the Smyth County Courthouse for Benjamin Allen, age 24, a farmer, and Polly A. Cruey, age 21, who were married 31 July 1888. Both were single. He was born in Smyth County, VA, she in Tazewell County, VA. His parents were Henry Allen and Ann. Her parents were Jack and Harriett. If I recall my other Allen records correctly, Henry's wife Ann had the surname Copenhaver.
