Hi Trish
This is the family I am trying to trace back. Judith is my gg grandmother. She had an illegitimate child (the granddaughter Mary in the 51 census), then married in 1850 William Simkin of Hallaton who was a widower.
In case you don't already have it, Mary was baptised at Tugby 28 May 1848, base born daughter of Judith, a spinster of Keythorpe Lodge.
Judith was baptised 5 Sep 1830 d/o William & Hannah of Keythorpe Lodge, Grazier
The baptisms of William & Hannah's children almost all describe him as a grazier of Keythorpe, except for Hannah 1823 which describes him as a labourer.
The earliest entry I can find for the Isset's of Keythorpe is the burial on 8 Sep 1699 at Tugby of Priscilla Isset, wife of Robert of Keythorpe. Prior to that there is a baptism of Thomas Isset on 4 Aug 1688, son of Robert & Priscilla - no abode given.
Robert may have married again following Priscilla's death:
2 Nov 1701 baptism John s/o Robert Isset of Keythorpe Lodge - buried 5 July 1702
26 Sep 1702 baptism Robert s/o Robert Isset of Keythorpe Lodge
8 Oct 1703 burial of
Jane, wife of Robert Isset
14 Oct 1703 baptism Edward, son of Robert Isset of Keythorpe Lodge
The only burial I can find for Robert is 26 Feb 1763: Robert Isset of Keythorpe, aged 88, which would fit with the death of Priscilla in 1699 but make him only 13 when Thomas was born in 1688, unless there's been a transcription error and it should be 1698
I also have the burial on 23 Mar 1750 of Ann, wife of Robert Isset of Keythorpe
I'm struggling to connect the generations to William baptised 21 Sep 1783, but they certainly seem to have a long connection to Keythorpe. The name Judith first appears in 1742 as the wife of William, and in 1744 (baptism of James) they are described as 'of Keythorpe'.
