Sophia Porter settled in 1839 at Glen Eden, a site now under Lake Texoma north of here. Her husband, early trader Holland Coffee, built a fine home where guests included Robert E. Lee, Ulysses S. Grant, and other army officers from 1845 to 1860. During the Civil War, she wined and dined passing Federal scouts and learned that they were seeking Colonel Jas. Bourland, Confederate defender of the Texas frontier. While her guests were busy, she slipped out, swam her horse across the icy Red River, warned Colonel Bourland, and helped prevent a Federal invasion of North Texas.
