Hi
Thank you for your message.
Do you know much about their emigration? The dates, the reason why they left, who they may have travelled with?..etc..Generally more information was given at the port of arrival rather than the port of departure. If you knew which city they arrived at (e.g. Liverpool, New York, etc.), this could be a good place to find more information.
Some site you might try - if you haven't already are:
Ellis Island: http://www.ellisisland.org/search/passSearch.asp
Castlegarden: http://www.castlegarden.org/
US National Archives/Immigration info: http://www.archives.gov/research/immigration/
The Boston Pilot; From October 1831 through October 1921, the Boston Pilot newspaper printed a ?Missing Friends? column with advertisements from people looking for ?lost? friends and relatives who had emigrated from Ireland to the United States. This extraordinary collection of 40,743 records is available here as a searchable online database, which contains a text record for each ad that appeared in the Pilot. http://infowanted.bc.edu/
Church records may be of some assistance. Most Catholic records are held locally - One site which might be of use is - http://www.irishtimes.com/ancestor/browse/ - where you can ?browse? an overview of available records per county. If you have any difficulty, you could try writing to the parish priest for possible assistance.
Civil registration records are available from the General Register Office (GRO). These start from 1864. You can access the website here: http://www.groireland.ie/research.htm
If you had a parish or townland location you could try checking the land records called the Tithe Applotment Books (1823-38) http://titheapplotmentbooks.nationalarchives.ie/search/tab/home.jsp or the later Griffith's Valuation (1848-64) http://www.askaboutireland.ie/griffith-valuation/ or the Church of Latter Day Saints (LDS) https://familysearch.org/ for various members of this family.

Remember to post as much information as you can with regard to the people you are researching. The more information you post, the more likely it is that one of our volunteers will be able to advise or assist you. Also include information concerning which sources you may have already used so others may further your search.
Please be patient - as our programme has only begun to rollout across the island of Ireland and volunteers in some areas may not yet be organized.
Kind regards,
