The profile has "About" information for "Elizabeth, Lady Scales".
Anthony Woodville married Elizabeth, Lady Scales some time before 4 April 1461. She died on September 2, 1473.
Woodville, by now Earl Rivers, then married Mary FitzLewis, daughter of Sir Henry Fitz-Lewis and Elizabeth Beaufort, c. 1480.
The dates for "Gwenllian Stradling" and "Margaret Wydeville" are seriously hashed. IF "Gwenllian" existed and IF she married him, it must have been before 1461. A birth date of "1442" for "Gwenllian" makes this uncomfortably tight, and a birth date of "1455" for "Margaret" makes it MUCH WORSE.
There is no reliable record, anywhere, of Anthony Woodville being a child bridegroom or having a child bride - let alone getting his child bride pregnant at an absurdly young age.
It has been claimed elsewhere that what was involved was not *marriage*, but a fling that resulted in a love-child. Dating for that could be more flexible and more plausible.
