Lucy Corker is mentioned in a book ( Boddie, John Bennett,. Seventeenth century Isle of Wight County, Virginia : a history of the county of Isle of Wight, Virginia, during the seventeenth century, including abstracts of the county records. Chicago: Chicago Law Print. Co., 1938. Page 213. ) as being the wife of William Corker and sister to John White. It doesn't give any information further on her, and mentions her husband's will being made in Surry on 14 Sep 1677. Getting a copy of that will might give you more information, it's probably available online somewhere.
