I can find no source for N.N. Mitchell. The following information is from Mayflower Births & Deaths* The children of Jacob Mitchell and Susanna Pope are:
Thomas
Jacob
Mary (m Samuel Kingman)
The son Thomas is sometimes called 'Thomas Curry Mitchell' and married Elizabeth Kingman Mitchell Their chidren are:
Thomas (m Ann Teague)
Henry
Timothy (m Deborah Packard)
Susanna (m Joseph Packard)
Edward
Elizabeth (m Alexander Wilson)
Mary (m & D unknown)
Seth (m Anne Latham)
I think that some merging/renaming needs to occur: Merge this profile with @Thomas Mitchell Curry, rename to either "Thomas Mitchell" or "Thomas Curry Mitchell" and correct the DOB and DOD as needed. That may also result in the need to merge this profile's spouse(s).
I am willing to take on this task if the current profile managers agree.
NOTE: There are three sources listed for this profile, but they are actually three citations to the same tree at GenealogieOnline (a Netherlands Web Site). It appears, however, that tree has either been removed or drastically changed. Personally, I do not believe that other trees should be cited as sources for this reason. These sources should be removed and correct sources added.
BTW, my wife (maiden name Mitchell) is a descendant of Experience Mitchell through his son Jacob. I am descendant of Experince Mitchell through Elizabeth Mitchell (John) Washburn.
