In reference to your marriage of Charlotte Deem to M. Turvey:
A Jackson Co., Ohio researcher gave me a report of a Charlotte Deem who married Mordecai Turvey (poss. Aug. 2, 1851). This Charlotte Deem is given as the daughter of Abraham Deem (s/o your Adam Deem Jr. & Hannah). Also, there is reportedly a marker in Jackson Twp., Jackson Co., Ohio for a Charlotte Turvey, who died in Dec. 1886 at the age of 43. If this is the same Charlotte, that would mean she was born about 1839.
I am related to these Deems through Fitzpatrick and Cramblit marriages in Jackson Co..
Is there any chance that the Charlotte Deem you have as the daughter of Adam Deem, was actually Adam's grand daughter?
