The name Guerin occurs in connection with the Clonmel settlement.

“Another name that has been suggested as connected with the Clonmel colony is that of Guerin. Jacob Guerin, the original refugee, came to England in 1563 from Normandy and settled in Canterbury. Other members of the family later followed him, of whom Samuel and Daniel were naturalized in 1682 and Francis in 1688, and it was possibly one of these who served under Lord Galway from 1691 to 1699 and was granted a pension of four shillings a day on the Irish Establishment although the identity of the pensioner cannot be established. A Solomon de Guerin with his wife Anne was naturalized in 1697, and his son Charles was baptized at Westminster in 1698. This family later removed to Dublin where the father died in 1709 and where the son entered Trinity College with a brother or cousin, Maynard Guerin. A Pierre Guerin appears as an elder of the French Church in St. Patrick's Cathedral from 1693 to 1710 who may have been connected with the family although he came from Macon in Burgundy. The will of a Gaspar Guerin was registered in Charleville in 1670, so that many Huguenots of this name seem to have settled in Ireland, and the writer has been informed that it was in existence in County Tipperary in the nineteenth century, although by then its bearers had become Roman Catholics.”^[12]

There is no record of a Huguenot family having the name Guerin settling in Killaloe. The nearest Huguenot Settlement was in Portarlington in the midlands and again there is no record of a Guerin in that Huguenot settlement.^[13]

Any individual Huguenot settling in Killaloe would most likely have worshipped in Killaloe C of I Cathedral. The Huguenot name Chevenix is to be found in that church register but not the name Guerin.

A thorough search through the Church of Ireland Register (1679 – 1845)^[14] for the Cathedral Parish of Killaloe found no Guerin (sic).
The names Gerane (1720) and Geran (1793), however, were found.
There is fifty (50) year gap (1733 – 1784) in the register when, apart for seven entries during the whole of 1742, no entries were made. However the name Guerin is not to be found either before or after this gap. The particular register runs up to 1845.
Some entries of interest were noted and recorded; see the following pages.

There is a Huguenot connection with the C of I. Cathedral of Killaloe but it does not involve the name Guerin.

“Some important Huguenot names are connected with Killaloe, where James Abbadie held the Deanery from 1699 to 1724 and Dr. Richard Chenevix the Bishopric before his translation to that of Waterford in 1745, where the history of his family has been recorded.”^[15]

Other names encountered of possible Huguenot origin were Prideux, Bouchier and Chambry.
