So "Mrs. D.F. Seaver" was Desire French (Simons) Seaver - a female, and a widow for 68 years at her death, who would normally be named as Mrs. Desire Seaver in the society columns of the 1920s, but was referred to as "Mrs. D.F." in this particular obituary.
Why was this obituary published in a Washington, D.C. newspaper? Her eldest son, George William Seaver (1844-1888) and his family had resided in Washington, D.C. and was buried in Glenwood Cemetery in 1888, along with his wife Nellie (Lathrop) Seaver who was buried there in 1925. Their son, William Earle Seaver (1889-1953), was a draftsman in the 1920 U.S. Census in Washington, and a patent attorney in the 1930 U.S. Census in Washington. She had family in Washington at the time of her death.
