Hi Steve,
I note William and Emma's application for free travel lists William aged 26 a Carpenter, Wife 23 and children (Son 3, Daughter 9 months)
1841 Census Shows William aged under 35 wife aged under 35 along with 1 son and 1 daughter are residing in Gilbert Street Adelaide.
Now I do find the marriage in Fowey
William
COUCH = Emma
JENKINS 29 Jan 1835
and the birth of a son John Jenkin
COUCH also in Fowey 10 Jan 1839
I note that this differs from the BISA - a very good resource for SA Research but it does contain errors as it was compiled in part by submitted information - this entry does have some unknowns.
