Irish Civil Registration index is back up this evening!
Looks better, but I don't think is right yet - it should be showing a marriage that took place at the Pro-Cathedral in 1878. The groom is there on the index but the bride isn't - it may of course be because the bride's details were never indexed. (It happens).
To check this out, could SKS please check on the microfilm or paper indexes and see if you can find a Teresa MCNALLY marrying a Daniel SHERIDAN in Jul/Sep 1878, North Dublin, Vol 2, Page 479. Daniel is there but Teresa still isn't.

I know the reference is correct, the marriage cert (showing both parties) arrived from Roscommon today.
