ALFRED RICHARD VIZE
Not sure about Charlotte, but Alfred Richard Vize married Mary Hatch Badcock 2 Aug 1839 in Shoreditch. They had three children:
Georgiana Mary Vize b abt Sep 1839 Hackney, m Henry Bradforth 4 Dec 1859 Islington, d abt Apr 1903 Wandsworth
Emily Augusta Vize b abt Sep 1841 Islington, m George Smallman 2 Mar 1860 Battle, d abt Sep 1920 Lambeth
Alfred Edward Vize b 12 Mar 1843 Islington, d abt Apr 1888 Lambeth.
1841 census - Alfred and Mary with baby Georgiana, also Alfred's mother Grace
1851 census - Alfred and Mary with 3 children
1861 census - Alfred "single lodger"; Mary living with son Alfred
1871 census - Alfred living with Charlotte; Mary living with son Alfred
Mary continued to use the name Mary Vize. She appear to be the Mary Vize who died in 1894 in Wandsworth.
There does not appear to be any marriage between Alfred and Charlotte (and in fact several of Alfred's children and grandchildren appear to have made similar arrangements).
ROSIE VIZE
Married Thomas William BRYAN on 14 Jun 1890. They don't appear to have had any children.
There is no evidence that she married Benjamin Babington PEAD as she appears to have stayed married to Thomas - she is named as "wife of Thomas William Bryan" in Ben's will.
She may have married William A MURRAY in 1924?
Benjamin's first wife's name is transcribed in many variable ways. Her maiden name appears to have been DUNN or DENNES depending on whose transcription you use. It is hard to see. Her married name has also been transcribed variably but it looks like "KEY" to me rather than "HEY". Her death was registered in Dec 1896, just before Ben gets together with Rosie.
