Katherine Conolly, Irish political hostess, landowner, and philanthropist, dies at Castletown House, Celbridge, County Kildare, on September 23, 1752.

Katherine Conolly is born Katherine Conyngham around 1662. Her parents are Sir Albert Conyngham and Margaret (née Leslie). She is the eldest of their ten children, with one of her brother’s being Henry Conyngham. Her maternal grandfather is Henry Leslie. She marries William Conolly in 1694, Speaker of the Irish House of Commons (1715-29) and purported to be the wealthiest man in Ireland. The marriage is likely to have been a love match. The couple uses her dowry of £2,300 to purchase their first estates in County Meath. Through her connections, her husband is able to ally himself with the influential Protestant families such as the Gores, Montgomerys and Leslies. She becomes known as a political hostess, gaining a mention in a ballad detailing the 1723 Westmeath by-election.

Upon the death of her husband in 1729, Connolly inherits estates in Wales, as well as in counties Meath, Roscommon, Westmeath and Kildare. She continues to be influential in Irish public affairs, being asked for her opinions and counsel. Living on Capel Street, Dublin, and at Castletown House, County Kildare, she entertains a large circle of friends. She carries on her husband’s plan to build the residential Collegiate School, Celbridge, built from 1733 to 1737, then supports the school with £50 each year. She commissions a monument in her husband’s memory by Thomas Carter, in Kildrought Church, Celbridge. She also commissions Conolly’s Folly in 1740 and The Wonderful Barn in 1743 to generate employment in the area.

Connolly dies in Castletown House on September 23, 1752. A portrait of her by Charles Jervas still hangs there. Upon hearing of her death, Mary Delany notes that her death “is a general loss. Her table was open to all her friends of all ranks and her purse to the poor … she was clever at business, and wrote all her own letters … she was a plain and vulgar woman in her manner but had very valuable qualities.”
