Looking for Griffith Family St Helier Jersey and Later Southampton

Hi everyone
I am looking for the descendents of John Griffith and Betsy Le Gresely whose family lived in St Helier Jersey (Channel Islands) for a few generations before some of them moved to Southampton around the late 1850's.
Children include:

1 John Tom b 1815 who married Elizabeth Jobe
2 Thomas John who married Ann Rose and emigrated to Australia
3 Betsey b 1820 who married Thomas Smith and moved to Southampton
4 Phillipe b 1822 who married Esther Elizabeth Shepherd and moved to Southampton
5 George b 1824 who married Emma Quarm (Littlejohn) and emigrated to Australia
6 Jane Mary b 1827 Nantes who married George Edmonds in Southampton
7 Henriette b 1831 who married John de Heaume Square
8 Francis William b 1833 who married Jane Collins
9 Mary Ann Jane Griffith b 1837
10 Ann Amelia b 1940
11 Emily Esther b 1842

often the name is incorrectly spelt Griffiths. Please contact me if you think any of these people fit into your family tree

Regards
