Thanks for those land tax records, John - will come back to them when I find the right moment!
I am going to start by making a few notes based on what I've found so far on the first group.
Family groups other than that of nephew Thomas
1. Cousin John Broomfield deceased and his daughter Sarah now the wife of Hollingdale
2. Brother in Law Thomas Soper, his son John Soper and his daughter Jane the wife of Heath Note: as mentioned by Guy the term brother in law has several meanings.
3. Late brother James Siffleet and his daughter Jemima
4. Nephew Michael Siffleet of Worth and his 2 daughters, Hannah the wife of Thomas Collens of Worth Yeoman and Elizabeth Sifleet, spinster
5. Christian Sturt and Thomas Sturt children of my Niece Elizabeth the Wife of William Sturt
6. Kinswoman Mary Gansey daughter of Detemia Gansey
7. Nathaniel Willy, Edward Willy, William Willy Richard Willy , Sarah Willy Elizabeth Willy and Mary Willy sons and Daughters of my Niece Elizabeth Willy
1. Re the Broomfield connection - I found this marriage but haven't managed to work out the connection yet. Maybe Thomas landowner's (TLO) father? That would make TLO only born about 13 years after the marriage, but he would have Broomfield cousins.
Name Thomas Siffleet
Event Date 12 Nov 1719
Event Place Horsted Keynes, Sussex, England
Spouse's Name Sarah Broomfield
2. My Soper family group concurs with this, except that upon looking at the script, deciphered "Hoath" rather than Heath, and found a burial of a Jane Hoath which seems to match:
Church name St George - Crowhurst (small village near Battle in East Sussex, although recorded as Surrey on FreeReg)
Burial date 17 Jun 1810
Person age 50
Burial person forename Jane
Burial person surname HOATH
And then, relating to no. 5, I have just found this record on FreeReg:
Place Henfield
Church name St Peter
Marriage date 27 Mar 1788
Groom forename William
Groom surname STURT
Groom condition bachelor
Groom parish Ashurst
Bride forename Elizabeth
Bride surname SOPER
Bride condition spinster
Bride parish Henfield
Witness Henry STURT
Witness Jane SOPER
Register note Licence. Groom William Sturt Junr
Does that latter note mean that the groom was under age, or...?
This one is tying my brain up in knots, because I'd initially created a sister Siffleet (possibly also a Jane?) to TLO who married a Soper and thus produced Jane Hoath (Soper) - but this is suggesting that Elizabeth Soper is the one who is the Soper and Sturt connection to the family. I need to ponder this further.
3. James and Jemima - tick.
4. Michael and co. (possibly that Micah - will return to that) - all good, except that I found a marriage record for Hannah which uses the Collins spelling (
https://familysearch.org/ark:/61903/1:1:N228-HXP):
Name Thomas Collins
Spouse's Name Hannah Siffleet
Event Date 08 Dec 1802
Event Place Worth,Sussex,England
5. Connected to the Sopers somehow - see above. Need to work on these.
6. Haven't looked at Ganseys yet.
7. Ditto Willys, although wondering about the niece relationship. There are quite a lot of Willys and variations of the name - will come back to that one.
Edit: I have found a marriage of a Jane Soper to a James Heath in Chichesterm oddly, recorded twice on different dates:
https://familysearch.org/ark:/61903/1:1:NX4D-N6F and
https://familysearch.org/ark:/61903/1:1:Q2Q4-3C5W (the latter perhaps a civil marriage, then the church marriage?). But the latter says she's a widow, so I think that rules her out. Just a strange coincidence?!
(That letter looks like a definite "o" to me, although I know that handwriting was different in those days.)
