Hi Christine -
I think I have the whole family for you -
in the 1851 census, St Helier, Jersey I found -
LOCK
John - head marr 28 iron founder born: Bath England
Hannah wife mar 27 - born: London
[Is this John a son of Samuel ?]
and in the same address but another household:
LOCK
Samuel head unm 18 coach, wheelwright born Guernsey
George brother unm 17 iron founder/apprentice Guernsey
Emily sister unm 15 dressmaker/apprentice Guernsey
Eliza sister unm 13 scholar Guernsey
Frederick brother unm 11 scholar
Harriet sister unm 9 scholar
Of course, Elizabeth [Lock]and William Mutton would have left for Australia by then, but I wondered if some of these are her siblings - particularly John who was born in Bath?
I looked in Channel Islands 1841 Jersey census online, but didn't find this family - but given the above information, I then looked in Guernsey and found them! -
St Peter Port, Guernsey, district 6: Glatney Esplanade
Saml. LOCK 40 Tailor E[ngland]
Sarah 38 E
John 18 Moulder E
Elizabeth 16 dress m E
Francis (F) 14 E
Salina [sic] 12 Y [Y = yes, born in Guernsey]
Samuel 10 Y
George 8 Y
Emily 6 Y
Eliza 4 Y
Frederic 2 Y
So this is where Samuel Lock was in 1841, and Elizabeth before she married and emigrated. Bearing in mind the 1841 ages are rounded, Samuel would have been born in England (Bath?) between approx 1796-1801, and Sarah two years later.
Good luck with looking up the Bath connections!
