I realise that this is a long time after your original posting but I have the following info, I know of a Gordon White who married Annie Lovell in Sri Lanka, I imagine they are the same as yours. My gt grandfather was Gordon's eldest brother who was John Hubbard White and who became a General in the Indian Army. Their father was a James Thomas White who ended his life working in Sri Lanka as a merchant in a firm called Robertson. Previously he lived in Guyana where he married hi American wife, Anne Gordon Hubbard, These were well to do planters and merchants. Their family arrived in the US in 1635 and can be found quite easily on the web. The Whites are a bit more vague. I think that James' father was Andrew who served as a surgeon in the English army in the Peninsular War (88th later Connaught Rangers)and also Italy, Greece and Egypt. He was one of the first 300 Fellows of the Royal College of Surgeons in England.
