"The first recorded instance?" Liz asked in thought "I don't know off the top of my had sorry. However, I do know the legend of how the first person got the ability if that will be any use." The girl paused for breath "Well, legend goes our family used to live away from society on an island, living at one with nature and all that rubbish. But, one day one of my past relatives was swimming in the ocean when he was knocked unconscious and drowned. However, while he was drowning he said he dreamt about meeting a fairy who told him she would use her magic to save him and when he arrived back on the island he had the water body and from then on descendants of that man could also turn into water." Liz finally finished her story "But yeah, thats all I know about it really."
