Hello Roger I am a professional genealogist and I live on Islay! I've spent about 20 years researching ALL Islay's families.  I now have a database with many tens of thousands of folks all with an Islay connection.  Maybe I will have some information for you. Please contact me off-list and I will do my best to help you. My apologies for the slow response - I've been away from home since before Christmas (actually in Virginia!) As AyeElaine Scott
