David told his granddaughter, Suzanne, that they pronounced it Umphrey like the English. This may explain why it has showed up in some census records that way.

David is the son of Hugh Humphrey and Elizabeth Lovell according to both "The Forsythe-Humphrey Story", and "A Book of Memories". He was born on March 16, 1856, in Vermont, McDonough County, Illinois. According to his tombstone and the Illinois Statewide Death Index, he died on January 21, 1924 at home. His daughter states in "The Forsythe-Humphrey Story" that he died at his home in Galesburg, Knox County, Illinois, not in Kankakee County, Illinois as the Illinois Statewide Death Index states. He is buried in Linwood Cemetery, Galesburg, Illinois.
Unpublished books written by his daughter incorrectly puts his marriage date in both 1870 and 1879, and his death date as January 2, 1924, but these are either scan errors, or are typographical errors, which seems likely since she typed all her works on an old manual typewriter when she was in her seventies.
Phoebe Jane Compton was the daughter of Jonathan Jesse Compton and Julia Ann Taylor. She was born on May 3, 1857, in Avon, Fulton County, Illinois. She is found living in Union Township, Avon, Fulton County, Illinois with her family in the 1870 Federal Illinois Census at the age of 13. She died on October 25, 1938 at the Soldier's Widow's and Daughter's Home, in Wilmington, Illinois not in Kankakee County, Illinois as the Illinois Statewide Death Index indicates. She is buried alongside her husband.

David later moved his barber shop to Maquon, Illinois, and then to old Brown's Hotel and the old Union Hotel in Galesburg, Illinois.
