Early Life of Sir Roger Mostyn

Gloddaeth Hall, Carnarvonshire (now Conwy), a home of the Mostyn family.

Roger Mostyn was born on July 31, 1673, in Flintshire, north Wales. He was the oldest son of Sir Thomas Mostyn, 2nd Baronet, and his mother, Bridget Savage.

He started his studies at Jesus College, Oxford in February 1690, when he was 15 years old. When his father passed away in 1692, Roger inherited his family title, called a baronetcy, and their large estates (lands and properties).

Even though the family had a lot of land and a good income, Roger enjoyed spending money. He especially loved horse racing. This led to some financial challenges for him. To help with this, he needed to make a good marriage. On July 20, 1703, he married Lady Essex Finch. She was the daughter of Daniel Finch, 2nd Earl of Nottingham.

Sir Roger Mostyn's Political Career

Sir Roger Mostyn became the Sheriff of Caernarvonshire in 1701. He was a member of the Tory political party. He supported his father-in-law, Daniel Finch, in politics.

In 1701, he tried to become a Member of Parliament (MP) for two different areas. He lost in one election but won the seat for Flintshire without anyone running against him. In 1702, he was elected MP for Flint and also for Cheshire. He chose to represent Cheshire.

He was also made Constable of Flint Castle in 1702. This was an important local position. In 1705, he voted on a special law. This vote might have caused him to lose his seat in Parliament and his job as Constable.

However, he was still able to represent Flint Boroughs. He was elected again for Flintshire in 1708 and 1710. In 1711, he became the paymaster for the marines, who were soldiers serving on ships. He voted on important trade laws in 1713.

Sir Roger was elected again for Flint Boroughs in 1713. From 1714 to 1716, he held a position called "teller of the exchequer." He also served as Custos Rotulorum of Flintshire from 1714 to 1717. This role meant he was the chief keeper of the county's records.

In 1715, he was appointed Constable of Flint Castle again. He held this job until 1728, when his son took over. He was re-elected for Flintshire in 1715, 1722, and 1727. In 1727, he became Custos Rotulorum of Flintshire again and kept this role until he died.

Sir Roger voted against some important laws, like the Excise Bill in 1733. He also supported changing a law that set how long Parliament members could serve. He decided to retire from Parliament in 1734.
