From online research, hopefully correct: [corrections requested]
Ferdinand Cortez Nealey (1863-1951) was born 15 March 1863 at Monroe, Maine, the son of Joseph T. and Lucy (Couillard) Nealey. The birth date comes from an unsourced mention on Ferdinand's FindaGrave memorial, and the place and his parents' names come from his marriage record.
At the time of the 1900 Census, Ferdinand was rooming at Belfast, Maine, and working as a photographer. He traveled throughout the state photographing civil officials, buildings and vistas.
Perhaps it was on such a trip to Aroostook County, Maine, that he met his future wife, Eva Germaine Nickerson (1878-1968), whom he married on 18 November 1902 at Caribou, Maine.
Eva was born 25 May 1878 at West Houlton, Maine, the daughter of Civil War veteran Henry Oscar Nickerson and Alice Julia (Estabrook) Nickerson, who were natives of Linneus, Maine; from information on Eva's FindaGrave memorial and marriage record.
Ferdinand and Eva made their home at Houlton, Maine, where they raised at least three children, a daughter and two sons, and Fred operated a photography studio.
Ferdinand died at Houlton in 1951; Eva died in 1968.
