Yes I am descended from David and Marion McBroom. There is a website I found that gives a history on the McBroom family, I don't know how accurate it is, as the person who wrote it insists that the McBrooms were neither highlanders or lowlanders, but that they were a small family that lived in a southwestern district called Galloway-
Everything else I have found indicates Kirkcudbright, though..... and also, I'm not very well educated on Scottish history, but I thought all people from scotland in that time period fell into either highland or lowland clans? But anyways, which line do you descend through?
