Sir John Rogerson is thought to have been born in Holland circa 1648, while his father was in exile there. He subsequently settled in London where, as a merchant, he was apparently as well known on Lombard Street as he later was in the Dublin Tholsel, so perhaps he was raised as a Londoner.
He was certainly living in Dublin by 1674 when listed as one of the first parishioners to attend the new church of St Andrew’s, just off Dame Street.
Sir John Rogerson’s first wife Elizabeth was the youngest daughter of Emmanuel Proby of St. Gregory, London. Her grandfather, Sir Peter Proby, was Lord Mayor of London in 1622, while her uncle Sir Heneage Proby was sometime MP of Buckingham. Her mother Mary was the daughter of London merchant John Bland. Their country residence was ‘The Glen’ or ‘Glasnevin House’ located just outside the village of Glasnevin. Rogerson also built the village church and allegedly made a few pennies from the tithes.
After Elizabeth's death, apparently from tuberculosis, John was married secondly circa 1696 to another Elizabeth. His new wife was Elizabeth Ward, daughter of John Ward (1611-1657) and Elizabeth Vincent (1628-1688). She died in 1726, two years after him.
There is a suggestion that John Rogerson may have suffered a double calamity in his final years. It is believed that his son William Rogerson of Peter Street / St. Werburgh's Church died of a fever on 3rd February 1721 and that Willam's infant son, also William, died on 12 May 1723. William's widow Alice (nee Mullineux / Molyneaux) was married secondly in 1723 to Sir Richard Wolseley (1696-1769) of Mount Wolseley, County Carlow.
We know Sir John had at least two more sons - John, who succeeded him and became Chief Justice of Ireland, and Richard Rogerson. The latter was born in London and educated in Dublin by various teachers for three years, before spending four years at Eton under Mr. Newborough. At the age of 16, he was admitted to Gonville & Caius College, Cambridge, as a pensioner to the bachelor's table on 15th April 1704, under the tutealge of Mr. Hawys. He was admitted at the Middle Temple on 3rd January 1703.
