Violet Stocking: the last of Alice and James' children?

Violet is the youngest child shown on the 1901 census with parents Alice and James STOCKING, who are said to have had 21 children in all. She is the 16th child for whom some formal link (via the census) can be made - although this isn't always foolproof. A Violet Rose M I was registered in December 1900 in Camberwell, and appears on the census aged five months. What happened to her after that? There is no obvious marriage record in FreeBMD (and it would take a long trawl through the other indexes as I don't know what date she may have married - the range is potentially very large). 

There are other STOCKING birth registrations after 1901 which may include children of James and Alice, but without corroborating evidence from the census, there is little chance of identifying which 'belong' to them. The 1911 census may help.
