H C Cornwell of Alabama

Henry C. Cornwell was born c 1849 in Alabama. All I kanow about Henry is that he married Roxie Boswell in 1877 Texas and they were on the 1880 Lamar county census. Henry was a carpenter and then I lost them...No idea where they went.

So he is my dead end or brickwall and I desperately need help with finding this couple. Anyone with any clues that will help?
