Some 1,166 marriage records dating from 1835 to 1881 have been transcribed from the Roman Catholic registers for O’Callaghan’s Mills Parish by Sharon Carberry and donated to County Clare Library. They are now available for viewing, free of charge, on the Library's excellent Genealogy website.
Sharon, from Virginia in the USA, transcribed the records from images of the register pages available at the National Library of Ireland's registers.nli.ie. She transcribed all the entries in this register.
The transcriptions can be searched by date or by the surname of bride or groom. You'll find them here: O'Callaghan's Mills Parish – Marriage records.
They join 6,236 transcriptions of baptisms in this parish during the same period. These were already available on the library's site and are also Sharon's work (she's been mighty busy since the NLI's website went live in July!). They can be found here: O'Callaghan's Mills Parish – Baptism records
