Stanford's an unusual name and I think there was only one in this timeframe (although there were 2 more in subsequent generations).
William Levis (who married Elizabeth, Stanford's daughter) was from Billesdon. Where did they go? I can't see subsequent burials for William and Elizabeth. There's a baptism of a daughter Elizabeth in Narborough, then possibly a son in Houghton on the Hill, then nothing. Is there any record of a death for Elizabeth? Did Elizabeth and William have a daughter Ann, who could have accidentally been described as a daughter rather than a granddaughter in Stanford's will?
I can't see any baptisms for an Ann Levis in an appropriate timeframe who could have been an illegitimate daughter of Stanford.
Jane (Stanford's widow) also left a will and mentioned children Thomas (living in Huncote), Mary (a spinster), Ann Bradshaw (Ann married John Bradshaw of Enderby in 1775) and Jane Jarvis (Jane married John Jarvis in Narborough in 1784). As stated above, Elizabeth Levis isn't mentioned. Is this because she wasn't Jane's daughter? Or because she was no longer alive? Or had simply fallen out with her stepmother?!
Elizabeth was provided for in her father's will but not in Jane's. If she did die in that intervening time period, it narrows it down to 1778 - 1785.
Those are some very good questions!
I've had no luck with any Ann Levis either, and Elizabeth was dead by 1785 if my guess is correct (see below).
Here goes what I've come up with in my research (and using a lot of imagination I guess):
- A William Levis was discharged on 26 Jul 1773 from the Royal Hospital in Chelsea. Aged 35 born in Leicester, he served 18 years and 6 months with the 1st foot guards. This very neatly fits with William Levis baptised 21 May 1774 in Houghton-on-the-Hill, and could explain the relatively long period of no child birth by his wife Elisabeth after their first child Elisabeth in 1761.
- A William (farmer, abode Fleet Fen, d. 1789) and Elizabeth Levis (d. 1782) are buried in Gedney Hill. This is quite some ways from Houghton-on-the-Hill (last sighting when son William was baptised in 1774), but fits my family lore that a William and Elizabeth came from Leicestershire to the Fenlands.
- And here is the link to my verified earliest ancestor: A William Leavis, gardener born around 1774, is buried in 1850 in the Elm parish. On the certificate of his second marriage in 1838 he lists his father as William Leavis, farmer.
Note that there is at least one more Billesdon Levis sightings in the Fenlands around this time period:
- An Amos Levis (transcribed 'Levice') aged about 63, sojourner, dies 1761 in Sutton St James (Spalding). Considering how unusual his first name is, I believe this is the Amos Levis baptised 1703 in Billesdon, whose daughter Hannah was baptised in Billesdon in 1751. Note that Sutton St James is only a stone's throw from the Fleet Fen where William the farmer lived for the last 7+ years of his life.
