In 1851 the census has them as follows:
Overstratton, South Petherton, Somerset
John ELLIOTT 28, ag lab
Susan ELLIOTT 29, glover(?)
George ELLIOTT 5
Mary Ann ELLIOTT 3
Ann ELLIOTT 1
all born South Petherton
Freereg has the birthdate of Emily ELLIOTT (who was on the ship but not born in time for the census) as 6 July 1851 and her baptism date as 10 August 1851.
FreeReg has a marriage for John and Ann EDMONDS at South Petherton, 15 September 1818.
Also these baptisms with parents John and Ann EDMONDS
13 Jun 1819 EDMONDS William
06 Jan 1822 EDMONDS Susan
28 Sep 1823 EDMONDS Joseph - I think his burial was 12 Feb 1826
Perhaps this is the burial for Ann
South Petherton, Ss Peter and Paul
Burial Date 22 Jun 1825
Ann EDMONDS, 28
There is a marriage in 1827 for a John EDMONDS, widower, to Mary STONE (no details given for her)
Did John ELLIOTT die in Australia as there are a number of public trees which suggest that Susan later married George KINGDOM in NSW?
