Although not closely related to them, the Grogan family of Westmeath, Dublin and Wicklow crossed paths with my own Dublin Courtenay family and with the Ryans of Ballymackeogh, Tipperary, who also intermarried with the Pennefathers of Newport, Tipperary, all of whom are ancestors of mine, so I've done a little research into them, using Burke's genealogies available online on Google Books, Ancestry.com and the Irish Genealogy website.
The earliest known member of this family was John Geoghegan of Co. Antrim who settled in Co. Wexford, and whose son was John Grogan, (1653 - 1720) who married twice. By his first wife, Anne Reynolds of Wexford, he had a son, Cornelius Grogan, from whom the Grogans of Johnstone Castle, Co. Wexford, descended.
Cornelius Grogan (1687 - 1724) married Elizabeth White of Ballyellis, Co. Wexford, and, by her, had John Grogan of Johnstone Castle who, on 6th September 1735, married his cousin Catherine Knox, the daughter of Andrew Knox and Mary Grogan. This John Grogan made a will in August 1775 which was proved on 10th April 1784 - he named his sons in order as Cornelius, George Knox Grogan (the mayor of Galway), William Grogan (he died in 1785), Thomas Knox Grogan who died in 1798 during the rebellion, John Knox Grogan (born in 1760, he married Elizabeth Geraldine Fitzgerald, the daughter of the late Stephen Fitzgerald of Ballythomas, Queen's County, in January 1803 - this from 'Saunders Newsletter', 5th January 1803)and Overstreet Grogan. John Grogan's will only named two of his daughters - Anne Ribton and Anna Maria Simon, whose husband was Stucky Simon, and who had a son James Simon. Other, unnamed daughters, were Catherine Grogan who married Vesey Colclough of Tintern Abbey, Mary Grogan who married Ebenezer Radford Rowe and Anne Grogan who married James White.
John Grogan's will also named a cousin as Lawrence Grogan.
The eldest son of John Grogan and Catherine Knox was Cornelius Grogan, at one time MP for Enniscorthy, who, caught up in the 1798 rebellion, was accused of treason, possibly erroneously, and was executed, aged about 70, on Wexford Bridge on 27th June 1798. He was buried in Rathaspeck graveyard adjoining his Johnstown estates; his property eventually passed to his nephew, John Grogan, and then to his grandnephew George Grogan Morgan who was alive in 1844.
A memorial plaque in St. Saviour's, Arklow, Co. Wicklow, commemorates these early members of the family, and their role in the Rebellion of 1798, although makes no mention of another of the eldest of the brothers, Cornelius Grogan:
'Sacred to the memory of Thomas Grogan Knox of Castletown, Co. Wexford Esq., who was killed at the head of his Corps with two others charging the rebels on 8th June 1798 under the command of the Honorable Major Gen'l Needham at the battle of Arklow....he fell in the defence of his King and County aged 41 years....having taken his degree in Trinity College, he purchased a Cornetcy in the 2nd Horse (now the 5th Dragoon Guards) and continued in it for 15 years. He raised the above Corps, the Castletown Yeoman Cavalry (64 members) the 31st October 1796,,,he was the second surviving son of the late John Grogan of Johnstown....who was for many years MP for the town of Enniscorthy. This...was erected by his brother, John Knox Grogan of Johnstown.'
John Knox Grogan, who erected the above memorial plaque, died aged 59 on 20th March 1815. His brother, Overstreet Grogan, a Dublin merchant, made a will in 1758 in which he named his brother, John Grogan, and his sister as Anna Maria, the wife of Stucky Simon. A cousin was Edward Grogan, and a brother or, more likely, brother-in-law, was Robert Carson.
To return to the earlier John Grogan, (1653 - 1720) who, following the death of his first wife Mary Reynolds, married a second time, his next wife being Anne Smith. Daughters were Mary Grogan who married Andrew Knox of Rathmacnee, and Sarah Grogan who married William Morgan, the mayor of Waterford. (William Morgan, alderman of Waterford, made a will in 1786 which named his wife as Sarah Grogan and his children as John, Samuel and Anne Morgan.)
The son of John Grogan (1653 - 1720)and Anne Smith was Edward Grogan of Ballytrain.
This Edward Grogan of Ballytrain, Wexford, had a son, also named Edward. The younger of the two Edwards settled in Raheny, Dublin, where he married Jane Grierson (28th February 1740/1 - November 22nd 1814), the daughter of George Grierson and Jane Blow, in St. Andrew's, Dublin, on 1st May 1762. He was a silk mercer.
Their children follow:
1) George Grogan who died in 1763; also Euphemia Grogan who died in 1764.
2) Janet Catherine Grogan, born 1766, married Sir Jonah Barrington in St. Werbergh's, Dublin, on 7th June 1789. See further detail below.
3) John Grogan of 10 Harcourt Street, Dublin, then of Tinakilly Lodge, Wicklow. (1770 - 1830). A barrister, he married Sarah Medlicott, the daughter of George Dowling Medlicott of Youngstown, Kildare, and of Sarah Meredyth. Sarah Meredyth was a direct descendant of Richard Meredyth who was appointed Bishop of Leighlin in 1589 and who had come to Ireland from Wales as chaplain to the Lord Deputy Sir John Perrott. Both the names 'Medlicott' and 'Meredyth' would be recur in later generations of the Grogan family as a middle name.
The Meredyth family has been extensively resesarched by Keith Winter and you can access his excellent website here:
John Grogan was buried in the family plot in Raheny.
