Elizabeth died after 4 Sep 1593 in London, London aged >41.
Her 1552 birth date is a hold-over from an erroneous mother (Mary Poole/Poore/Poley) for Stephen, erroneously copied on many trees. Elizabeth got married 1579 and it doesn't look like she was married before and there's no way of telling her age (or John's). If she was born in '52 she'd have been 27. That was old for a first marriage back then.
We don't know her actual birth or death dates or locations or parents. The Morgan Williams and the Elizabeth Breyton in the real world weren't even in the same generation, much less married to each other or parents of the Elizabeth Williams who married John Hopkins. Morgan Williams did have a daughter named Elizabeth who married Robert Whitney. Elizabeth Breyton was the GRANDMOTHER of Morgan's daughter's husband. Research the mother of Sybil Baskerville.
In Winchester, the widow Elizabeth was appointed administrator of John Hopkins's estate (he having died end of August since his inventory was 4 September 1593) on 4 October 1593, with William Hopkins (probably not Stephen's older half-brother since he was born around 1575 and wouldn't be of age) signing the bond.
There is no such place as "Duglam, England" which you'll see quite often in copied trees from Ancestry.com.
