Re: Hannah from NC/ son David born in Dyer Co. TN
I am also descended from David Burnham through his daughter, Margaret (Burnham) Troy who married Edgar Troy and moved to Independence Co., AR and then to Heber Springs, Cleburne County, AR.
Unfortunately I don't have anything concrete, but I believe his father to be Joseph Burnham who married Hannah McPherson in 1816 in Dyer Co., TN.(She was the widow of Jonathon McPherson of Williamson Co., TN, who died in 1815 in the Battle of New Orleans).This is the only Hannah I have found who matches up with a Burnham in the right area and time frame.I believe Joseph must have died soon after their marriage and that David may be their only child.
I believe Hannah had a child, George Washington McPherson, with her first husband.
