Chesterfield Township is in present-day Fulton County, although the county was not formed until the mid -1850s.
He is not listed in the Early Obituary Index, beginning in 1839, at http://www.rootsweb.ancestry.com/~ohfulton/early_obits.html#...
I checked http://chroniclingamerica.loc.gov/
, selecting Ohio, the dates from 3/3/1849 to 12/31/1849 and CRAWFORD and zero hits were shown.
If any of his descendants remained in Chesterfield Twp. through 1888, you may be able to find their location on this plat map; http://www.historicmapworks.com/Map/US/169905/Chesterfield+T...
