Hi Leslie,
Thank you very much for your message. I hope that someone with information on the family makes a connection with you and helps you to further your research.
In the meantime, have you tried looking in church records for information? Most Catholic records are held locally so you may need to write to the local parish priest for possible assistance. One website that you may find useful is the Irish Times where they give an overview of what records are available in specific parishes. It also shows you where copies of the records are available. For Loughrea parish, follow this link:

For Kilmovee:

The Tithe Applotment Books (1823-1838) found at http://titheapplotmentbooks.nationalarchives.ie/search/tab/home.jsp
