Gray

I am searching the Gray name.

The brick wall that  have hit is with Peter Gray-He was born in Chemny (according to newspaper obit) County New York about 1813-1814.

He died in Griffin Missouri in October 30th 1902. I tried to find a Death certificate but in about 1920 all records were burned in a fire in Missouri.

I am trying to locate his parents.

Any Ideas?
