Hello, my name is Charlotte Melinda Madill. My father is Keneth madill, and he and his family are Canadian. I think that his very close family are in Montreal but you can find them all over Canada. My dad Kenny's grandma was a charlotte madill on his fathers side. His father is John Arthur madill. I dont know if any of this has anything to do with your research! My father hasn't heard of any of the madill's that you have listed. Sorry if this is no help but i thought i better tell you! Regards, Charlotte Madill.
