We have some rich relatives
Gran Nicolls brother Ed went to India in the time of the Raj and became in mums words very grand and very rich.
Grans husband Bob did not like him much, mainly because he stayed in India in the first world war instead of coming home to fight.
His Grandaughter is Sally Croker Poole.Mum remembers as a 14 year old visiting her at her parents home in Surrey. Sally at that stage was crawling around the floor as a baby.
