Thompson family from London to India and then South Africa.

Hello.  My name is Jean Fiona Thompson.  My father was Gilbert Nelson Thompson born India in 1937, his father was Harold Montague Thompson Married to Jeanetta Angus Thompson.  Someone has just given me a huge update on this family line.  I am interested in the Thompson Genealogy if anyone has anything to add to this I would be so greatful.  I am particularly interested in Katherine Montague Thompson who had a son called Montague Thompson.
