Not quite sure how "Holcraft" turned into "Welbeck" but I guess there's some logic in there somewhere..
I suspect that site has simply pasted the wrong info onto the page. There's a place in Nottinghamshire called Welbeck, while a Beck is a name for a stream / watercourse and I'd guess you get wells along watercourses. So the Holcroft link has no logic to me at all.
Interestingly Welbeck is a much more common surname in Ghana than England, though as a former British colony I imagine the origin is still the same.
