Henry Everitt is listed in the 1883 Fargo city directory as a photographer, living at the Stanton House on NP Avenue. He is no longer found in Fargo after 1883.
There is a Henry Everett listed as a photographer in Chicago, in the 1880 Census. He was born in England around 1837. It is possible that this is the same man who was listed in Fargo in 1883.
