Gene,
Could your Nancy be the dau of Stephen and Hannah? I would think so as they were in Shawnee county when Nancy married. They had a dau in the census named Nancy b. ca 1842 IN. AND...most all the Ogans in KS in Shawnee and Jefferson Co desc. from Stepen and Samuel of IN.
If you know of a male descendant who bears the Ogan surname, you may wish to have them do the DNA testing to see if there is a connection. Someone on Samuel Ogan of VA, OH, & IN (from whom Stephen descends) is being tested now. If your relative could match, you are probably on the right track.
Write me directly if you want to share more info on your line.
