Seeking Family of Margaret Adams Abt 1771 1866

Hello all,
I am researching my paternal line which contains references to Cythiana Lucus, daughter of JOSIAH LUCAS 1838 Ohio, and MARGARET ADAMS 1771 - 1866 (est dates).
Old family letters tell of Cynthiana attending a dance at which a Peter Boyalton Adams attended and danced with her. Her mother (MARGARET told her he was a cousin).
I can not find anything else to document this other than other old family letters and stories.

If anyone can help, please let me know.

I am currently posting many of my documents on my website at www.cagleonline.com

I also have a world atlas printed in 1927 that may help someone find old place names. I would be happy to scan and send any map it contains, but as I would scan in hi-def, the files are too large for the website, so please contact me.
