You can find some Gregory history here http://www.dcnyhistory.org/http://www.dcnyhistory.org/ if we are looking for the same Gregorys. I think we are because of Russell and Timothy Gregroy. The Samuel S. Gregroy buried in the Harvard Cemetery at the East Branch, Colchester, Delaware County was born in 1865 died in 1947, Married to Minnie V. Roosa (later family name changes to Rose)Her parents were Martin N. and Lillian Roosa. The acers of land owned by the Gregorys was called Gregorytown and they have their own cemetery there.
"The names of the heads of the several families settled on the Colchester section of the Delaware before the Revolution , so far as we have been able to ascertain, were Jacob Barnhart, Frederick Miller, Daniel Wilson, William Commins, Silas Parish, Daniel Bowker, Russell Gregory, William Rose and Timothy Gregory;"
