From the Wrestlingworth PR transcript, marriage 27 Jan 1812 Thomas Stephens of Cockayne Hatley to Elizabeth Hummerson of Wrestlingworth. This was the only Stevens/Stephens name in the Wrestlingworth register. I did notice another marriage on 15 Nov 1804 of William Hummerston to Martha James, he may be related to Elizabeth.
The same volume had the Cockayne Hatley transcript and has baptisms/burials of Stepping(s)/Stebbing as follows.....
Children of John & Susan Stebbing
3 Apr 1768 Thomas - buried 22 Jan 1771
19 Nov 1769 William - buried 1 Feb 1771
Susanna wife of John Stebbing, farmer buried 20 Jan 1771
Two other children of John Stebbing were buried, Mary 20 Jan 1771 & John 26 Jan 1771 but I cannot find the baptisms. Seems Susanna & 4 children got buried as a job lot over 12 days.
Then John Stebbings, widower married Mary Cubiss on 14 June 1771
Children of John & Mary Stebbing.....
29 Mar 1772 Mary **
8 Jan 1775 Thomas - buried 5 Oct 1781
24 Aug 1777 Sarah - buried 30 Sept 1781
26 Dec 1780 William - buried 22 Jan 1804 as Steppings
6 Jan 1782 Sarah **
... now of John & Mary Stepping/s
7 Mar 1784 Thomas
15 Oct 1785 Samuel
10 Oct 1790 James
** Possibly Mary Stepping married Thomas Bartle on 1 Nov 1792 and Sarah Stepping married James Timson of Everton on 12 Oct 1804
Finally John Stebbings buried 27 Mar 1808 aged 79
That all being said this does not necessarily prove that Thomas Steppings is the Thomas Stephens who married in Wrestlingworth but most likely it is.
Cheers John
