Thanks Arjem, Yes that will of Leonard Stevenson's 1830 contains the clear statement that Christopher is his son: and Esther (Day) is Leonard's wife: and this is the same Christopher Stevenson.
The question then is:
Is this Leonard Stevenson the son of Thomas Stevenson and Mary Kilburn, born 19 May 1757 - as most people with Ancestry trees seem to assume:
OR is he Leonard Stevenson, son of Leonard (Innholder) and Jane of Hallaton, as named 'my only son and heir' in their Leics Archdeaconry wills of 1764 (Leonard bap 26 Dec 1749, brother of Allen, bap 11 Feb 1755 who presumably decd. as not named).
Probably Thomas and Mary, but is there any confirmation of that?
Christopher Stevenson of Hallaton, youngest son of Leonard Stevenson and Esther Day, married Lucy Waddington at Medbourne 1815. Lucy Waddington was daughter of John Waddington, cooper, and his wife Lydia Gibbins of Medbourne, who m there 9 Oct 1792.
