I just found the baptism as Rosie replied but then looked for a marriage.
I can't be certain but there is one that fits:-
Newington, Surrey (8 miles from Chiswick) 4th March 1863
William Harvey, mariner, father John Harvey, mariner.
Mary Jane Crocker, spinster, father Jese (sic) Crocker, labourer.
Witnesses - Emma Harvey and George Millitt?
On the 1851 census, there is a Jessy Crocker with a six year old daughter, Jane, in Dorset.
In 1861, Jesse is in Poole but no Jane.
May just be a coincidence.
