I believe I have found Mary Dover in 1900. She is indexed as Mary A. Doors, is living at Wood Station in Catoosa County, GA. She is 51 years old, widowed, head of house, born August 1848. She has living with her: James "W?" (should be "J") Dover, born August 1873 (additional info to follow on him), age 26, farm laborer, Belton Dover, born Feb ?, farm laborer, and Francis C. Dover, b. February 1887 (I think). Marjorie Dover Stansel
