I do not know the middle name of Newton E. Akin for sure but according to Decatur County, Tennessee History and Families 1996, he did have a half sister Permelia who married William P. Bray. Is the Permelia you are referring to the one who married a William Bray in Davidson County, TN in 1830. This same history says his middle name is Edward. In the 1820 Maury Co TN William V. Akin did have 2 females age 0-10 in his household. You can e-mail me at Jackie279@yahoo.com and I will give you the name of a person that is researching Newton E. Akin line.
