The original glass plate negative is a little ill, to say the least, but couldn't resist this one for the obvious glamour of the wedding party. All that we originally knew about this photo was that it was probably the wedding of Miss Watts of Bonmahon, Co. Waterford. This may be the Watts family who had copper mining concerns at Bonmahon (Bunmahon).
Confirmation about the wedding has come in from DannyM8, along with a very dramatic and quite tragic local story. See the comments below for detail. But now we know that Miss Watts was Emily Blanche Watts (1878-1960?), known as Blanche, who married Thomas Francis Buckley. I've added notes on the photos on the couple who were presumably the bride and groom, and on maybe Blanche's mother and brother, based on 1901 census information provided by DannyM8.
