My great great grandmother was Mary I Della Rockefellar Humphrey, she was called Della. She was born April 10, 1859 and died January 8, 1945. Born in Bolivar, NY to Francis and Esther Rockefellar. She had a brother, Frank J Rockefellar from Millport, PA and a daughter, Mrs Charles Edel from Olean, NY. Her only grandaughter was Arlyeen Edel Haug, an army nurse and Lieutenant.Della's father was born in 1820 and died in 1909. His father was Robert Rockefellar and mother Ruth Jacob. Della's mother was born in 1834 and died in 1919. Her mothers maiden name was Pierce. Della was married to George Humphrey from Partageville, NY. I would appreciate any information as to how or if she was related to Nelson Rockefellar. Any info on cousins or what type of work the family did. Thank you!
