States: Texas: Williamson
You didn't include much information in your query, but since Gradington looks like a less common name I went looking. On the 1930 census for Williamson Co, TX there are only two named Gradington, one is a teenager and probably a son of the older man. Both are listed as black, is that your family? If so, might I suggest you include that in your queries, it really helps to narrow down searches. Going back to the 1900 census, several head of households named Gradington and still all are listed as black.
Happy Hunting (^_^)
