I M Looking for Information on David Kelley Born About 1786 IN New York I Have Every Thing Up to Who His Parents OR Siblings Are Any Help Would Be...

Hi,
I'm searching my 5th grade grandfather David Kelley dob 1797 in Pennsylvania. I have been unable to find a town or county. David married Rebecca Risch, I have not found a date on the marriage, Rebecca was also born in Pennsylvania. I found these birth places from there son James Allen Kelleys death records.
Both David and Rebecca moved to Ohio I believe the town / city was Van Buren.
James dob-Sept 8th, 1848,Hanover,Ohio.Dod-Sept 16th,1927, Putnam County, Lepsic, Ohio.

Any information would be greatly appreciated.
