Have been looking at a family for ages tonight feeling sure I am wrong but here we go..
I looked for a Julia and Annie and came up with the Joseph(s)family 1891
https://www.familysearch.org/ark:/61903/1:1:3T7V-66ZLooking at the children on this census, Julia and Louis birth as Cannonbury, Elizabeth Aldgate, I think MMN is Levy which could be the marriage of JJ to Hannah Levy Q1 1886 London City
Joseph occ butcher
JJ is still in Middlesex St. to 1892 (electoral reg.) and then JJ and Louis can be found in Liverpool 1901, occ butcher, married
RG13/3417/59/55
1911 JJ is an antiques dealer still with Louis and JJ still married

Have absolutely no idea about Maurice but finding an Elizabeth in the household 1891 got me searching!
Just noting also that it looks like JJ died back in Middlesex 1924 from the probate calendar
