My 3x great-grandfather Patrick Creedan was from County Cork, Ireland. He had at least two children baptized in Clondrohid Parish in County Cork with his wife Mary Coakley. Patrick's daughter Julia was baptized there in 1842 and his daughter Honora in 1848. His son Timothy was born in 1846, but those records seem to be missing.
Patrick was born on March 17, 1814 according to his tombstone. I found a couple of possibilities for baptism records for him on the National Library of Ireland site. On Page 37 of Microfilm 5002/05, there were two Patricks baptized in March 1814 in Clondrohid.
The first Patrick was baptized on March 8, 1814 to parents Tim and Julian Creedan in Clondrohid, County Cork. The address given was Carigapuca and the sponsors were Michael Buckley and Johanna Creedan. The second Patrick was baptized on March 14, 1814 to parents Dennis and Mary Creedan. The address was Baurthanaknuck and sponsors were Timothy Murphy and Johanna Creedan. No maiden names were given for the mothers. The Creedan spelling seems to be the most common in this area, but I've seen Creeden and Creedon in some of the other locations.
Since my Patrick had children named Timothy and Julia, the first one seems like the best possibility. The first one also has the same address as that given when Patrick's daughters Julia and Hanora were baptized. If his tombstone is correct, neither of these is quite a match for a baptism date, but I didn't see any other good matches for the months following March. Also of interest on this page, there are several Coakleys. Patrick married Mary Coakley sometime before July 1842, but I haven't found a marriage record for them so far.
