Hi Kimbee!
I found the following births on FamilySearch.org:
Mary Kate Caulfield 10 Mar 1880 in Cork, Cork, daughter of Richard Caulfield and Kate Coughlan
James Caulfield 24 Feb 1878 in Cork, son of Richard Caulfield and Catherine Coughlan
Sarah Caulfield 28 Jul 1866 in Queenstown, Cork, daughter of Richard Caulfield and Catherine Coghland
as well as this marriage:
Richard Caulfield and Catherine Coughlan on 14 Oct 1865 in Cork, Cork
As far as I'm concerned, my ancestors were a William Caulfield born in Irleand around 1872 and a Catherine Poole who married in Cardiff in 1900. According to their marriage certificate, William's father was a Richard Caulfield, a diver, deceased before the marriage. Does this ring any bells with you?
Merry Christmas
Andy
