Fitzgerald/Penrose Fitzgerald (Corkbeg)
- In 1667 Garrett Fitzgerald was granted the castle, town and lands of Kilcorkbegg alias Corkbeg with other lands in the barony of Imokilly, county Cork. Robert Fitzgerald of Lisquinlan and Corkbeg, county Cork, settled his Corkbeg estate by deed dated 30 April 1715 and his Lisquinlan estate by his will dated 10 June 1718 on his grandnephew, Robert Uniacke, son of Thomas Uniacke, MP. Robert assumed the name of Fitzgerald and married Frances Judkin of Greenhills, county Tipperary as his first wife. They had two sons, the younger of whom became Sir Thomas Fitzgerald Judkin of Lisheen, county Tipperary in 1801. The elder son, Robert Uniacke Fitzgerald of Lisquinlan and Corkbeg, had one son, Robert Uniacke Fitzgerald, who married Gertrude, daughter of Thomas Lyon of Watercastle, Queen's County (Laois) and of Mount Blakeney but they had no children. Mrs Fitzgerald owned an estate in the parish of Kilbreedy Minor, barony of Coshma, county Limerick at the time of Griffith's Valuation. In 1794, R.U. Fitzgerald's eldest sister, Louisa, married James Penrose of Woodhill, county Cork. Their daughter, Anne Penrose, married Thomas Stewart and came to possess the Mount Blakeney estate and their son, Robert Uniacke Penrose-Fitzgerald, held land at the time of Griffith's Valuation in the parishes of Castlemagner, barony of Duhallow and Buttevant, barony of Orrery and Kilmore but the bulk of his estate was in the barony of Imokilly where he held land in at least seven parishes. In May 1852, 1,770 acres in the baronies of Barrymore, Orrery and Kilmore, Fermoy, Duhallow and Imokilly, county Cork, the estate of Robert Uniacke Penrose Fitzgerald was advertised for sale. In the 1870s his son, Robert U.Penrose Fitzgerald of Corkbeg, Whitegate, owned 5,307 acres in county Cork and 764 acres in Queen's County (Laois). In 1896 Robert U.P. Fitzgerald was created a baronet.
- This was the senior branch of the Penroses of Cork, descended from a Cornish Quaker family of that name. In 1732 John Penrose married Anne, daughter of Edward Cooper of Cooper's Hill, county Laois. Their son, Cooper Penrose of Woodhill, Cork, married Elizabeth Dennis of Cork and had a son, John. In 1794 John married Louisa, daughter of Robert Uniacke-Fitzgerald of Corkbeg and Lisquinlan, county Cork. The Cooper Penrose collection of art, containing portraits of this family, is now located at the Crawford Art Gallery, Cork.
- Hugo Read writes that in the mid 18th century John Dennis, a Quaker, was a timber merchant in Cork. He married Sarah Newenham and had an only child Elizabeth who married in 1763 Cooper Penrose. Through this marriage the Penroses inherited property in Cork city. Another member of this family was James Dennis, Baron Tracton of Tracton Abbey. Born in 1721 he was the son of John Dennis, a timber merchant of Kinsale and his wife Anne Bullen. James Dennis became a barrister and later a Member of Parliament. He was also legal adviser to the Earl of Shannon and in 1781 was made a Baron. In 1769 he married Elizabeth Piggott, daughter of Edmund Piggott of Chetwynd, county Cork. When Baron Tracton died in 1782 without an heir he left his estate in county Kerry to his eldest nephew the Reverend Meade Swift and his estates in counties Cork and Dublin to his other nephew John Swift, both of whom took the additional surname of Dennis. At the time of Griffith's Valuation James Dennis held an estate in the parishes of Carrigaline, Rathcooney and St Annes Shandon, barony of Cork, county Cork. In the 1870s the representatives of James Denis owned 1,029 acres in county Cork.
