I am pretty sure my great-grandmother was a DOW, and as Crawford County is near Warren County, PA perhaps she is descendant of one of the persons listed as offspring of Willis Dow.
My great-grandmother in question was Mary [Dow?] b. in Penna. in 1865 married William WAID (also b. PA 1865) family in Tidioute, Warren Co., PA in 1900 census with children Ralph Dow Waid (my maternal grandfather 1888-1933) Hazel K. Waid 1889-1976, Kenneth L. Waid (b. 1892) Georgianna Waid (b. 1894) and Harriett C. Waid (1896-1980).Household also included an Agnes Dow, b. June 1883.
Family may also have lived in Butler Co. (Butler) PA and Venango Co. (Oil City) PA.
Pls let me know if you find a Mary Dow b. 1865.Thanks!
