Jo: I found your grandmother on the 1900 Census for Indian Territory, Township 3 North, Range 10 East, Choctaw Nation: George W. Sorrells b. Aug. 1865 Ind. Terr. Catherine b. Sept, 1867 Ind. Terr. Lewis F. b. Dec. 1884 (as noted on his tombstone, but not 1884 as you noted in your posting) Ind. Terr. Ada b. Jan, 1888 Ind. Terr. Dora b. June, 1890 Ind. Terr. Irma b. June, 1893 Ind. Terr. The census showed that George and Catherine had been married 13 years, so they either married probably early in the year of 1887. Hope you can use this information.
