Joan Norys is said to have married 28 January 1615 (South Broom, Wiltshire) to Robert Cloud or William Cloud. Their son was the immigrant William Cloud (born 1621; died 1702, Delaware).
However, I have been unable to find the 1615 marriage record to determine whether Joan's husband was named Robert or William.
Also, I'm skeptical that the immigrant William Cloud had a middle name (Robert). I can find no record indicating he had a middle name.
