Hi Kristen, I agree there are problems with this branch.
No sources attached to her profile, although my research concluded that "Anne Fitzherbert" (of unknown parentage) married Robert de Digby Jr. (son of Robert de Digby et de Tilton, Sr. and his first cousin, Christiana the daughter of Everard of Tilton and Unknown wife)
Christiana's father Everard was the brother of William of Tilton. Their grandfather was Aelmar of Tilton, the progenitor of the Tilton/Digby lines.
I was unable to find any dates for her birth and death. And I only found one child for her: Sir John de Digby, Sr. (m. Arabella Herecourt, parents unknown other than the surname).
Of course this was just my own research, with which I constructed my own, 'corrected' line for my ancestral Digbys. I was unable to merge mine with the established line though, due to discrepancies such as this which would take too much time imho to correct, since much of it is unsubstantiated (no valid sources on view or attached to the relevant individual profiles).
So, since my hypothetical line based on personal research doesn't match well with the one here, I left it unconnected and place all of my profiles on "private" mode so they aren't accidentally merged.
But I'm happy you raised the question, and sorry I don't have more information on her at this time. Personally, I would remove her birth and death dates, remove her unproven parentage, and remove all the unproven children (except for Sir John, who is proven).
I'm not advising for or against doing that, just stating that if I had any say in it, and thought that it would be well received -- that's what I would do for now, until more sources are brought in for proof of these dates and relationships.
Sincerely, Debra
And now I must correct myself: the other sons are proven, after all. But I maintain that her dates and parentage remain unproven. I should have read the About beforehand.

Oops, she is "Ida", daughter of John Fitzherbert, according to this book's pedigree chart.
Beyond that, my own research varies slightly from this source, and I couldn't say which is more valid. Much of even professional level genealogy is essentially only educated conjecture and opinion, which inevitably leads to discrepancies, misunderstandings, and occasional controversies. That is the biggest drawback to collaborative work, imo, as it may lead to power struggles and unfortunately sometimes hurt feelings or bruised egos (which I try to avoid at all cost, lol).
Wish I could have been more helpful, I tried anyway. :)
