From my understanding my great great great grandfather moved from the Isle of Man to Scotland in the 1800's and my last name was spelt MacElroy at that time, later corrupted to McElroy when my great great grandfather moved to Ireland 20 years later. His name I believe was Mervyn Arthur McElroy. Any help with any information on names, dates etc on any MacElroy (which may be a corrupted version too) from the Isle of Man in the 1800's or early is very much appreciated. Thank you
