Hi Mark, how are you progressing with your research. Ihave just enjoyed reading "The History of Kirk Maughold" by William and Constance Radcliffe, which has a lot about the Kerruish's in it and which I purchased from St Pauls bookshop (I.O.M.)for approx $35.00Aus. I am descended from The Cardle Kerruish's of Maughold down through the Maltby Kerruish's of Douglas and my father and his father emigrated to W.A. in 1904. All the best in trying to sort out your rootsI would be delighted to find others who fit into this line
