I detached John Belgrave's parents almost two years ago, per the "disputed parents" paragraph. Somebody re-attached them, and I have just detached them again, per wikitree policy: No supporting information, and two conflicting GUESSES about the parents. ("Uncertain" parents shouldn't be attached just based on a guess, even if it is a guess that somebody posted on a website.)
As always, if further information based on primary sources comes up, this can be reviewed and changed.
