Transcriptions of Kilmurry Ibrickan's Roman Catholic marriage registers, 1839–1845 have been added to the Clare County Library's Local Studies website. Two indexes have been created, one arranged by Groom's surname, the other by Bride's surname. They are free to view.
They've been transcribed by Marie Crowley of Derry, who's already worked her way through the baptism registers for 1839–1880. I assume she's now intending to work through the marriage register.
UPDATE - 8 June: Marie is working at quite a pace. She's already added all marriages to 1850!
