Hi,
Do you think it could be a second marriage for one or both of them? I have found this possible marriage,
John BROWN Mar Q 1849 Greenwich 5 274
other names with same reference,
William BRITTEN
Eliza GOWERS
Eliza NOBLE
James PECK
Mary Ann UNDERDOWN
+
John AMOS
Rhoda GRAVES
I can find John and Rhoda AMOS in Greenwich in 1851.
Regards
Daisy
