Hi all, this is a fascinating and incredibly well sourced string of comments. I have been doing a one name study on the Lalor clan of Laois, which has also looked at what happened to them after some were transplanted to Kerry in 1608. The Lalors were one of the seven septs of Laois. Under the O'Mores they spent much of the 16th century fighting the English until their defeat in 1601. A planter and adventurer of Irish ancestry named Patrick Crosbie, who had lands in Laois and Kerry took of the task of transplating the most troublesome members of the septs to Kerry. His story is told in this article by Lord Walter Fitzgerald in 1923:

His brother John Crosbie was Bishop of Ardfert 1600-1621, and was married to Winifred (oonah) O'Lalor of Laois. See the Lalors of Cregg pedigree in Burke's Landed Gentry.
Her sister, Honora was married to Thomas Cantillon of Ballyheigue. She and two other Lalors - Timothy (Teig) and Daniel (Donnell) were recorded in his post mortem inquistion in 1613. The details of this PMI - along with a fanciful and fascinating maternal line recorded in an old O'Connell pedigree - is recorded in an article on the Cantillons by Antoin Murphy:

They are mentioned as fighting on both sides in the 1640s wars (a Captain Lalor burnt down the Ardfert Cathedral). But then tthere is no record till the mid 1700s.
The Ardfert Wills index lists a Daniel Lalor in 1746. He is, I suspect, the Daniel Lawlor of Traly who conformed to the CHurch of Ireland 17/8/1746, probably to secure the inheritance of his sons. His sons may have included James Lawlor MD of Castlelough, and Jeremiah Lawlor of Ballyheigue, ancestor of the Lawlors of Tralee. The history of this latter branch is recorded by 19th century antiquarian Henry Cairnes Lawlor:
