Some news on the Baker front.....
I had a reply from Cedric's old school in Bedford who have kindly looked through their records and among other things, confirmed that his previous school was Mistress Phillips Private School, Mussoorie, N India. (can't find a trace of it anywhere) So the family did return to India after Cedric's birth in 1897 and this would explain their absence from the 1901 census. The school also said that his father, William had already died by the time Cedric started in May 1909.
May is a bit of an odd time to start a new school so I guess that he started school straight after returning from India. If you had children needing to start new schools I would have thought that you would return to fit in, as far as possible, with new school years (September) unless the return was unexpected.....
