The Walsh or Walshe family in Ireland originated from Wales, the Walshes of Killincarrig were descended from the Walshes of Ballauly and Carrickmines Co Dublin. Ballauly is located between Dundrum and Sandyford in Co Dublin.

Henry Walshe

The first recorded Walsh at Killincarrig was Henry Walsh of Suttonston (an old name for Killincarrig), and was recorded in 1566 as leasing part of Dalkey. When Henry died in 1570 he owned two castles and two small fields in Dalkey, as well as one messuage and forty acres in Kilencargye. A massuage was a dwelling house with outbuildings with land attached.

Theobald Walsh

Henry’s son and heir Theobald is believed to have built Killincarrig Castle, though some say it was his father Henry who built Killincarrig House. Theobald was regarded as one of the leading men in the barony of Rathdown. He was married twice firstly to Anne nee Allen and this marriage produced six children. He second marriage was to Jane nee Eustace. Theobald died in 1620 and his eldest son was Henry Walsh.

Henry and John Walsh

Theobalds son Henry Walsh who married Margaret Walsh the daughter of John Walsh of Shanganagh. Henry and Margaret had twelve children, seven sons and five daughters. Henry died in 1634 and was succeeded by his son John, who was recorded as being one of 80 men involved in the Rebellion in County Wicklow. John was later indicted of Treason. John was married to Eleanor nee Walsh the sister of Theobald Walsh of Carrickmines. John would appear to have been the last Walsh at Killincarrig and Killincarrig House. He was referred to as a gentleman and had several tenants in the locality of Killincarrig and in the area around Kilcoole. He was recorded as having land confiscated in the Barony of Newcastle.
