Alice Fits John buried 17 Oct 1729 at Potton, Edward on 22 Nov 1734. So it's a fair bet that Edward was a widower on marriage in 1730.
Don't you just love these Ancestry trees where Edward is shown as born 1692 Baldock, died 1693 or 1694, spouse Alice, married 1716. Is any thought at all put into them? The best that can be said is that as Baldock is only 10 miles from Potton it might be the same Edward (but only if he didn't die in 1694!)
