I've looked through my past searches and come up with the following:
1901 Census - 31 St. Luke's Road, Clapham, Battersea; Ecclesiastic District of St James:
Agnes Amer 50 Cambridgeshire, England Wife Battersea London
Charles Amer 46 Royston, Hertfordshire, England Head Battersea London

1871 England Census
Charles Amer 16 Royston, Hertfordshire, England Son Therfield Hertfordshire
George Amer 7 Royston, Hertfordshire, England Son Therfield Hertfordshire
Henry Amer 18 Royston, Hertfordshire, England Son Therfield Hertfordshire
Jane Amer 14 Royston, Hertfordshire, England Daughter Therfield Hertfordshire
John Amer 49 Bromham, Wiltshire, England Head Therfield Hertfordshire
Sarah Amer 48 Newsells, Hertfordshire, England Wife Therfield Hertfordshire
William Amer 20 Royston, Hertfordshire, England Son Therfield Hertfordshire

I'm also pretty sure that I have the details of Charles and Agnes marriage by banns at St Mary at Lambeth, but I'll have to look for notes, so reply to this post if you are still searching.
