Does any body have any information on a watercolour artist called KR Heath?

I have a water colour by KR Heath, of a scene in the south of France, outside the town of St Paul. No date on it but I thought 1920/30s. There's also some information about a Mrs KR Heath who exhibited in Sydney, Australia. An advert suggests that she was based in London and describes her paintings of being "of many countries", which fits with my watercolour being of France. I'd be interested to know what painting(s) you have by her.
