The paternal ancestors of Arthur B. Rowan, evangelical clergyman, conservative politician and antiquarian (1800-1861), lived around Castlegregory, on the Dingle Peninsula. A soldier by the name of Shiercliffe secured lands around Castlegregory formerly belonging to Maurice Hussey who lost his life in the defence of Minard Castle during the Cromwell wars. Shiercliffe’s grandson married Sarah Rowan, granddaughter of George Rowan, the first of the Rowans in Kerry.
Of George Rowan we learn the following from Annie Rowan (Kerry Evening Post, October 19, 1898), daughter of the antiquarian. “George Rowan was a member of a Derry family who had been amongst those who held Derry against King James. When the siege was raised Captain George Rowan marched with William’s army to the South, came to Kerry, married Mary Blennerhassett and remained in the county.”
Sarah Rowan had a sister Mary who married William Mullins. Shiercliffe died without issue and his Castlegregory estate reverted to his father-in-law George Rowan. Around the year 1800, John Rowan, the great-grandson of George Rowan, sold the estate to his relative Mullins, Lord Ventry.
