Every source we have shows her as daughter of Sir Richard Croft, banneret and/or Sir Richard Croft of Croft Castle, which is the same thing. The citation which calls her "Jane da. of Sir Richard Croft of Croft Castle, Herefs." should not be dismissed in favour of no source at all. The cross means the member's details have not been entered yet, not that the relationship is dubious. Given that her husband was the chamberlain of Queen Catherine of Aragon and was an influential man of the court, and based much of the time in London, it would be very strange for his wife to be the daughter of a local Wilts. man we can find no records of whatsoever -- a complete blank. Also, her husband's niece married the son of Sir Richard Croft of Croft Castle, so the family connection was certainly there. (I have posted half a dozen or so of these sources already.)
On the other hand, I have hunted for hours and have found not even one source that shows her as daughter of a Crofts of Wiltshire. So far as I can see, the man exists only in unsourced online trees. Which is not good enough for Wikitree! Someone carelessly put him on a tree years ago and he has been copied over and over without question ever since. If anyone can find enough reasonable sources for a Wiltshire Jane to weigh against a Herefordshire one, great, let's weigh them up. So far there is nothing.
