I was surprised when someone from the British High Commission informed me that this search tool for lonely hearts is a legacy of the Raj. Until early 19th century, it was perfectly acceptable for the Brits posted out to India to take local women as wives and "go native". The "bibis" produced children who comfortably drifted between two cultures and inherited considerable sums of money from their fathers. But the interfering missionaries soon put a stop to that and made such marriages morally reprehensible.
