Norman, I believe the Austin b 1849 and the Austin who m Dicy are 2 different men.As mentioned...1880 Austin was single, not widowed/divorced.
Austin b 1817 VA was m to ?; he then m. 9-28-1865 Mrs Jane TUBBERVILLE, Johnson Co TX [adj to Parker Co]; she apparently d and he then m Dicy WOOLERY [possibly Mrs]. It is Jane's son, John TUBBERVILLE, living with Austin/Dicy in 1880. Chas Edw HICKS b Wise Co....his 1943 DC states parents: Austin HICKS/Dicey EARLEY. I can see where EARLEY/WOOLERY might get butchered in records. Phyl....volunteer
