Samuel b1771 SC married Dorcas Starr. They were in Maury and Williamson Cos TN c1800. They moved to KY at least long enough to have one son and came back to TN.
Their son, Arthur Stewart Akin, had moved to southeast AR by 1850.
The earliest Akin / Eakin / Aiken family in SC had a large plantation named Akinfield and was near Charleston. They consistently spelled their name "Akin". The earliest grant to them was a Proprietory Grant in 1697 to Thomas Akin. His sons were: John, Thomas, and James. Widow was Elizabeth. Daughters were Sarah, Mary, Martha, and Elizabeth Jr. They seem to disappear when the 1271 acre Akinfield is sold to John Huger in 1784.
Leonard Andrea makes a reference to Arthur Akin in Glynn Co GA, so I looked in Camden and Glynn Cos and discovered that some of those Akins ended up in Ga across the river from the Abbeville SC area. I tend to believe that they were loyalists and may have been forced out of SC.
