I still think my earlier 1861 find is a very good match for the Shoreditch marriage - are you sure your Mary Ann was nee Robertson?
This looks like your family this time:
1871RG10/629 108 28
St Mary Magdalen Bermondsey, London
26 Brandon StGeorge Jacobs, head, 41, Shoemaker, b. Salisbury
Mary Ann, wife, 37, b. Margate
Charles, son, 11, Errand Boy, b. Lambeth
Mary Ann, dau, 9, scholar, b. Newington
James, son, 7, scholar, b. do.
Elizabeth, dau, 4, b; Bermondsey
Struggling to find them in 1861 for now
