My grandmother was Edna Blanche Maitland who was born in Calcutta 8th March 1903 to John and Georgiana Letitia Maitland. He was a police officer and they kept a boarding house. Other than that, I have no other information. It would seem that Charles George Maitland may have been her older brother? Family anecdotal evidence suggests that John was Scottish and had arrived in India via NovaScotia, where he lived with his parents after leaving Scotland.
Please contact me if you have any further information.
