I believe the first Doolin (we spell it Doolan) that came to the US was a Joseph Doolin baptized in Rathvilley on May 8, 1829. Parents listed as traveling merchants John and Margt (Pierce)....see attached baptismal record. I also found a Pat Doolin baptized in Tinryland on Aug 8, 1841 with identical parents name. Would welcome any info, suggestions, on the Doolin line and looking for confirmation that the two baptisms listed are the same couple (parents).
