I would recommend using the US Census data which are now at Ancestry.com through 1930 If you can find your extended family in the US (assuming you are in the US), your chances of finding a 4th or 5th cousin who has papers from the 1800s. I was able to find 4th cousins in two of my lines who had letters and/or journals from the 1800s which served to pinpoint where their grandparents and/or parents lived in Ireland. **************Create a Home Theater Like the Pros.
