I have been fairly successful at tracking down all the women who married into my branch of the Crumley family except for Lucinda Byce died 1873 in Greene County, Tennessee. She was married to Allen W. Crumley.
The Crumleys started in Frederick County, Virginia before moving on to Greene County. They were Scots/Irish and frequently moved and married with the Johnston/Brown families of Winchester, VA & Greene County, TN. Members of these families moved to Independence AR after the Civil War and then on to TX by 1900.
Good Luck to all Byce families. It looks like there isn't much out there. I spent years looking for the Browns and Johnstons until I gave up. A couple of years went by and they were easy to find. Let's hope that by sharing our information we can help each other!
