Can't help with parish record, however there is this marriage notice:
"MONTAGUE - LEWIN. - On the 15th inst. at Brixton,
Arthur Wm. Montague to Amelia Jane, only daughter
of Arthur Lewin, late of St. Mary Bourne."
Wednesday, Jan. 24, 1894, Southampton Herald
There is a notice about an Arthur W MONTAGUE in Navy Appointments being appointed to the Excellent in 1886 - a possibility?
Also, in case you don't know, there is an article about the inquest into Arthur LEWIN's wife Jane's death in 1883. Happy to transcribe or send you a copy if you'd like.
