Robert Judkins - How many wives?

I see Ann Judkins attached and MP'd with 4 children:
Elizabeth Jones Hunt (Judkins);
Robert Judkins;
Sarah Judkins and
William Judkins
and I believe this Sarah Sarah Judkins is the "Sarah daughter of Robert Judkins" named in the will of Edward Petway Edward Pettway, of Surry but Edward is the father-in-law to Robert's brother Samuel.

Where can I find sources for Ann Petway and who is she to Edward?

Also, Wikitree and FAG show a wife Elizabeth unknown or Elizabeth Taylor who married James Stanton (Staunton) after the death of Robert
