Jim, I would like to see your compilation of Bartlett information. We have not been able to find any information on our Barlett line in Maryland between about 1804 to 1817 and this is the period during which the children were born to John Bartlett. My mother was born a Bartlett and was one of thirteen children, seven of them brothers. Three of the brothers (my uncles) are still living and I have many Bartlett cousins. The line is well populated. I might be able to persuade one of them to take the DNA test.
