I am not a decendant of the line that you are researching, but I have quite a bit of information on the Bartletts of Warren Co. IN.
The Carlinda Jane Mitchell you are looking at was the 1st of three wives for William Bartlett.They were married on 17-Apr-1842 (copy of marriage record on file at the Warren Co., IN clerks office).She later died in 1873.They had seven children, five of which were still living at the time of William's death on 26-Mar-1880.
William's obit indicates the same 07-Feb-1819 date of birth that you have listed for him, but it says that he was born in Frederick Co., VA near Green Brier.
Let me know if you would like any more information about the children, but I'm afraid I don't have anything maternal / paternal for Carlinda.
