TALLMADGE, Ohio -- Some members of the Ohio Genealogical Society are fanning across the state to document the graves of all Revolutionary War veterans in their counties.

Kelly Coghan Holderbaum, president of the group's Summit County chapter, said volunteers are searching for graves and taking pictures of what they find to help put together an accurate account of the men who helped create the United States.

Volunteers use genealogical information and government records to locate graves.

E. Paul Morehouse, president of the Ohio Genealogical Society, said there are probably thousands of Revolutionary War veterans buried in Ohio.

He says most of the graves are more than 150 years old and many of the headstones have disintegrated. In other cases, old cemeteries no longer exist.
