I know very little abt Wm. & Susanna. I do know they had issue: my gggrandfather, Robt. S., Wm. H., who d. unm 1856, Nancy, Elizabeth, & Mary. Surnames of the daus' husbands were: Malone, Reed, & Savoy. Tradition is Wm's father was Robt. & his mother's surname was Williams, both from Bath Co., VA. Have found no trace of Robt. There was another family of Wynns in Pike Co., descendants of Wm. S. Wynn, who arr. there < 1810. Large family. Wish I could be more help.
