Found a marriage
Richard Hoye and Elizabeth Mackey it so can't be a coincidence William named his third son Richard, maybe Richard isn't Robert's father but he chose him to be I think Robert was certainly born before the marriage.

ERRRRR both widow and widower curiosier and curiosier
Edit to say:
A few trees on Ancestry but none of them have Robert listed maybe he was their little secret or Elizabeth's little secret.
When I started this thread I didn't think I would find much information been a bit of a dead end for ages - or that anyone would either but it's been absolutely brilliant still haven't gotten to the bottom of the Hoye/Mackey problem probably never will but at least its a gate that has been unlocked mostly and very much by Kiterunner though rather than me I have to say
