Hi Sikes.
On Familysearch.Org there are these Children christened to JOSEPH/MARY Ridley in Luckington;
ANN 27 May 1764
THOMAS 22 June 1766
MARY 9 April 1769
JOHN 15 December 1771
I searched 1761-1781
Now even though John was christened Dec 1771 and Mary Ridley, Widow, married Joseph Vizer May 1771 is doesnt mean that all this info is incorrect.
(it would be interesting to see if it says Father deceased on that christening)
Mary may have had John early 1771 and he was not christened until after she remarried.
I cant find a Burial for Thomas Ridley c 1770 on line and as I am not in England cant help with a look up in Parish Records.
Did your Mary marry 1791 to Joseph Roundthwait ?
