Westport marriages 1823-57 are on LDS film 1279210. To find a film number for yourself, go to familysearch.org, click on Library, then Library catalog, then Place search. Enter Westport in first box and Mayo in second and enter to see all Westport films. Select Church records, then click on Parochial register and View film notes. You can also do this through the Irishtimes.com site, going through Ancestor, Roman Catholic parishes, etc., which is more user friendly, but they take their LDS information off the LDS site so there's one more risk of a typo.
