Still trying to find Grandmother in 1911

My Grandmother Susan Janover born 14 May 1901 5 Avenue Road Lower Clapton Hackney .

Lydia Rose her unmarried Mother is here in 1911 but no Susan

Anybody have any ideas where she might be thanks

Silly question perhaps but would she have been listed in maybe a Jewish School records?
