I am looking for William Alcorn, born in Donegal around 1865 - he was 36 in the 1901 census in Scotland. His wife was Margaret Mcaleese. They emigrated to Greenock near Glasgow and then later in life returned to Ireland. We believe he died in Belfast but don't know the year. His sons were William Henry, Thomas, and two more whose names we don't know. Any information anyone has would be very much appreciated.
