Unfortunately Sue, the newspaper article you have linked to, is behind a paywall, and I can't see it.
However Elizabeth did have about 10 children with her second husband Humphrey de Bohun, Earl of Hereford, and she has many descendants up to today (including possibly me), so having many people with her as an ancestor would be entirely possible.
Having said that newspapers are fairly notorious for getting it wrong and basing their lists of descendants or relationships on very basic research, so I wouldn't like to be adding profiles to WikiTree just based on the newspaper article alone.
