Thomas Spring

Thomas Spring of Castlemaine (died 1597) was an English Protestant soldier, landowner and Constable of Castlemaine in County Kerry, Ireland.

Thomas Spring was born in Lavenham, Suffolk, the son of clothier Thomas Spring. He was the great-grandson of Thomas Spring of Lavenham, the richest merchant in England during the early 1500s.

Spring was an officer in the army of Elizabeth I during the Tudor conquest of Ireland. He served with distinction, and as part of the Plantation of Munster he was granted over 3,000 acres of land in County Kerry in 1578. His land increased to approximately 6,000 acres when, on 12 December 1588, he was granted the estates of Killagha Abbey, which had been seized by The Crown during the dissolution of the monasteries. Spring was instructed to rebuild the abbey in a castle-like manner, so that it could serve as a defensive structure. He also became constable of the castle over the River Maine, with responsibility for maintaining English royal authority over the locality. He was accorded the right to hold several country fairs as a source of income and was in control of collecting tolls and taxes for the Crown. In 1585 Spring represented Kerry in the Irish House of Commons and he served as High Sheriff of Kerry in 1592. He was the first of the Spring family to settle in Ireland.

Spring married Annabelle Browne, the daughter of John Browne, Master of Awney, Co.Limerick, with whom he had two sons.His eldest son, Thomas, was a practising lawyer. His younger son, Walter, served as High Sheriff of Kerry in 1609. Walter's grandson was Walter Spring, who lost much of the family's Irish estate during the Irish Confederate Wars.
