Sorry, Rodny. there is nno such thing. but there are early stories of the marriage, even to the minister who performed it.But as to the actual day, that hasn't been recorded to a certainty. I don't know why. There are some recordings as to who attended the marriage, like two of her brothers, Nantequas and Porchins, and her 1/2 uncle, the 1/2 brother of her father, and his name was Opechancanough, and maybe another brother named Cornstalk. the exact number of Powhatan's children is not known and most of them were 1/2 brothers and sisters do to the number of wives that Powhatan had. You can find the story in many early Jamestown and Virginia Histories. Also see the William & Mary Series #1 Index. That should help pinpoint the info you need. There was a ship's Captain there and Captain John Smith wrote about it but I think he was back in England when he wrote it.
