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.
Have you checked the information to be found in the 1901 and 1911 census records. You can find this here: http://www.census.nationalarchives.ie/search/ in an attempt to identify her relatives?
you might also try contacting the local parish offices for assistance in puting your request in the local newsletter...?
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 make sure you link anyone else in your family who is interested in their Irish heritage to our site - and indeed anyone else you know of Irish heritage.
