Martha is a corruption of the word 'mother.' Among the hill tribes of the Cotswold's in Britain, throughout the Bronze Age, all women were named Martha. Your Martha was your wife. Few in England remember these stories of the Martha Cult or speak of the time when fettered and unfettered Marthas roamed the land, marauding and making merry and marrying at will. Centuries of stigma and public floggings have seen to that. All they really did was force all those Marthas underground.
One lone character, Martha Farquhar, a colorful television personality, kept the old tradition alive for the masses for many decades. He first came to prominence because he could bang on like nobody's business and could paint rustic murals with nothing but his beard and a tin of British paint. He said a lot of things, sang a lot of songs, but was fondest of saying, "I'm not just a Martha, I'm a Martha Farquhar." Quite the controversial type was our Martha.
Further evidence exists today, in the New Guinea Highlands, where the same tradition is still practiced although, with the introduction of Christianity by missionaries in the 15th Century, the name Martha has been changed to Mary. If you shout 'Hey Mary!' in the main street, every woman within earshot will turn and look straight at you. It's kinda fun.
