Westport RC parish is Oughaval (Aughaval) civil parish. Baptisms 1845-1905 and marriages 1823-1905 are on LDS films 1279910, items 17-22, and 1279911, items 1-4. Baptisms 1848-1873 and marriages 1825-1860 are also available on line (go to the Irish Ancestors site and click on Counties, Catholic records, Aughaval) but I don't know if they're complete for those years. FYI: There are only three Flanagans in Oughaval in the Griffith's index. One might be Mary Jane's father. Diane
