According to the subscription site Roots Ireland, the marriage was June 6 1853 in Arklow which was likely Anne's parish. Arklow is in the southeast part of the county.
Catherine's baptismal record in 1859 was in the RC parish of Valleymount in the northwest part of the county which includes the civil parish of Inch. I did not locate any other baptismal records for siblings.
Did the family emigrate?
