I have a Caroline/Carolyn BARTLETT (according to the 1850 Missouri census) born in OH.Her date of birth changes with each census - possibly 1820.We have found no BARTLETT family that claims her.
Her son was named Richard Bartles Ellington. We suspect that a censustaker may have confused the Bartles in Carolin's name with Bartlett.
There is no marriage record for Caroline to Thomas Jefferson Ellington because the part of Kentucky where they may have been married was suffering floods at that time and the records were possibly washed away.They later lived in Greenup Co. KY.
Their children were named: Ellen, Richard Bartles (we just found this out), Henry, Marion Enoch, Sarah and Armilda and were born in Platte Co., MO.
I noticed the Caroline in your record and wonder if they might possibly have had another Caroline in the family.
