I have your Robert Hazard Perry, born July 29, 1873 in Hamilton County, NY and married to Nelly M. Buyce, born May 1875 (exact place unknown). They lived in Wells, Hamilton County, NY.
Robert and Nelly had Lewis G. Perry and Leon M. Perry. Leon married Agnes Lena Conway and had Robert Leo Perry and Leona Perry. Leo's family lives in the Owego, NY area and is the family of my husband's cousin's wife.
Going back to Robert and Nelly, Robert's parents were George W. Perry and Jeanette "Nettie" Deming.
Nelly's parents were Myron H. Byce and Marcy C. Kibler Burnham (she was adopted by a Mr. Burnham when her parents died).
Hope this helps!
