Charles Preston Gainor (1892-1963) is pictured above on 12 February 1896. Preston, as he was known, was born in Baltimore, the son of Summers Everett Gainor (1862-1945) and Katherine Kennedy Brannon (1864-1916).
Preston married Alma M. Saucier Theriault (1890-1982), a native of Aroostook County, ME and a daughter of Pierre Saucier (1846-1920) and Marguerite Pinette (1860-1920). There were no children. Alma had come to Washington, DC with her then-husband Fred W. Theriault (1877-1958), also a native of Aroostook County.
Preston was the administrative assistant to the Chief Clerk of the U. S. Court of Appeals for the District of Columbia when he retired in 1950. He and Alma moved to Selby-on-the-Bay, MD and lived there at least until Preston died. Alma’s last known address was in Seal Beach, CA.
Summers was a brother of Hunter Boyd Gainor (1859-1928) who was a husband of Clara Beall Taylor Gainor Magruder (1881-1972), the subject of a post from 13 March 2017. This is a strange coincidence given that I bought the photographs from two different shops and a year and a half apart.
