I saw this 1857 ROCHE-FOLEY marriage record while looking for FOLEYS in Co. Limerick. This couple apppears to be no connection to the ones I was researching (Mary/Hanora FOLEY married Michael DUNNE before 1860 and lived Ballylanders parish, Co. Limerick; baptised son Michael DUNNE Jr. in 1860 at Ballylanders R.C. church), but they might fit into your family or someone else's.
Kilfinnane parish R.C. church marriage record:
Thomas ROCHE and Hanora FOLEY married at the Roman Catholic church in Kilfinnane parish, Co. Limerick, July 21, 1857. Witnesses were William Roche and John Foley (probably fathers or brothers of the married couple).
