Where do you live? I am in Kent, England. What records are held in Cambridge?
John Thomas KEYT moved over to the Straits Settlements about 1866 and worked in the Colonial Office in Perak then in Singapore. He married Iris Constance SCOTT who died in Penang in 1942. Don't know what happened to John Thomas but the all their daughters,grand and great grand children (including my mother) were born in Kuala Lumpur.
There must be some records somewhere about families who lived in Penang and the Straits Settlements.
How are you related and do you have any information about the SCOTT in your post?
Look forward to hearing from you. My direct email is firstname.lastname@example.org
