Hello again,
I have looked to see if there are any more baptisms for this couple and cannot find any in Frome for the period around 1800. There are baptisms of children by William and Elizabeth DAVIS in Nunney however. Nunney is about 3-4 miles from Frome at most.
All Saints, Nunney.
12/06/1791 James DAVIS, son of William and Elizabeth DAVIS.
11/05/1794 Robert, son of William and Elizabeth DAVIS.
25/03/1796 Samuel, son of William and Elizabeth DAVIS.
22/03/1798 Lucy, daughter of William and Elizabeth DAVIS.
12/05/1799 Henrietta, daughter of William and Elizabeth DAVIS.
13/02/1801 William Henry, son of William and Elizabeth DAVIS.
03/04/1803 Mary Frances, daughter of William and Elizabeth DAVIS.
Also, a marriage at Nunney on 22/05/1785 William DAVIS, to Elizabeth TURNER.
A search on Freereg will produce many more Davis relatives I suspect. There is another site for the Frome Local Group which covers Frome and Nunney which has many parish registers.
