Daughters of William & Helena:
Laura Florence Baker b. 12 Jan 1881 India. She is not on the 1901 census, so I think travelled back to India at the same time as mum and Cedric. Shows up on the English 1911 census aged 30, single living with mum, Helena in Bedford. In 1932 she is still "Miss LF Baker" on Cedric's army record, living in Sutton, Surrey.
Mabel Irene Franziska Baker b. 30 Nov 1886 India. She is on the 1901 census, left behind with the neighbours in Bedford. Can't find her in 1911. In 1923 she is described as "Mrs M Lilley" living in Bournemouth
