Somewhere in my search I also found your "Guy"--have you checked www.familysearch.com
? seems like it was there. Also, check the census for that area in the nearest census year. Those are the places I look the most. Could be they are related. My Guy was born in Illinois but his father, Henry Blackburn Nunamaker was born in PA--1828; Mother--Mary Staley, born also 1828 in PA.
