Hi
I've been checking the IGI as my cds turned up nothing and found the following:
Edward Sanson b. c1734 of Charlton (date/place confirmed in Phillimores) Wiltshire m. Israel Palmer 25 Oct 1759 Great, or Broad Somerford, Wiltshire. His name is given in another record as Sansom.
Israel is given a birth of c 1738 Great, or Broad Somerford.
Further checks on IGI (at familysearch):
Israel Palmer b. 18 April 1744 Christian Malford. Parents William Palmer and Rebecca.
In my regs for Christian Malford (Phillimores) I have found William Palmer m. Rebekah Ody lic. 4 Mar 1731. Also on IGI as 1730/31
Rebbeca Ody chr.4 Jul 1708 parents William Ody and Jeane/Jane Trimmell. IGI then goes back as follows:
Jane Trimmell chr 18 May 1676 Christian Malford. Parents William Trimmell and Lucy Webb. Marriage to William Ody 12 Apr 1705.
William Trimmell b. c 1643, d. 24 Feb 1703/4 Christian Malford. Parents William Trimmell and Ann. Marriage to Lucy Webb 25 Jun 1669 Christian Malford.
William Trimmell b 1617 Christian Malford., d. c1671. Marriage c 1642
Lucy Webb b. 6 Dec 1644 Bromham Wilts, d. 3 Jun 1702 Christian M, burial 7th Jun 1702 CM. Parents William Webb and Lucy Paradise.
I will leave it at this point as it goes a bit further back to 1500s and you should be able to access IGI (familysearch.org). I know IGI isn't perfect or complete but it's a good starting point. Also had a quick look on WorldConnect at rootsweb, just plugged in Lucy Paradise and someone has posted family there including siblings etc so again worth a look
Also check out this site
http://history.wiltshire.gov.uk/smr/getsmr.php?id=2275 which refers to 'Trimnell's Farm is associated with William Trimmell AD1642. References in A2A, the government archives site indicates other Trimmells with land in Wilts in 16/1700s so it seems they must have had land and a bit of money!
Hope this is all some help.
Regards
Steph
