If you are looking to find Ulster Scotts Ancestors in county Antrim then look no further than the National Archives of Ireland. As they have recently gone on-line with the 1911 census many of Northern Ireland counties including Antrim are now active. The census is a great tool for family research, so have a look! Our local library and Museum are always available to assist you in your search. Just ask at Reception for information.
