I'm looking for a death record for Sarah A. Johnson, born Sarah A. Estey. In 1900, she was living in Wantage, Sussex County, NJ. But in 1915, Sarah's husband John H. was living with son George E. and his family in Ontario County, NY without Sarah, so presumably she had passed on by that time.
Sarah was born about 1835, and her husband John was born in 1848. Son George E. was born in 1873.
Any help would be appreciated.
