Mostyn baronets



The Mostyn baronets are two lines of Welsh baronets holding baronetcies created in 1660 and 1670, both in the Baronetage of England. One creation is extant as of 2015. The two lines are related and both claim descent from Edwin of Tegeingl, an 11th-century lord of Tegeingl, a territory which approximates modern Flintshire.

Mostyn of Mostyn


The Mostyn Baronetcy, of Mostyn in the County of Flint, was created in the Baronetage of England on 3 August 1660 for Roger Mostyn. The second Baronet sat as Member of Parliament for Caernarfon. The third Baronet represented Flintshire, Flint and Cheshire in the House of Commons and served as Lord-Lieutenant of Flintshire.

The fourth, fifth and sixth Baronets all sat as Members of Parliament for Flintshire. Ann Mostyn, daughter of the fourth Baronet, married Thomas Pennant of Downing Hall. The fifth Baronet was also Lord-Lieutenant of Flintshire. The title became extinct on the death of the sixth Baronet in 1831. Elizabeth, sister of the sixth Baronet, married Sir Edward Pryce Lloyd, 2nd Baronet. In 1831 he was created Baron Mostyn, to which the Lloyd Mostyn Baronetcy is a subsidiary title.

Mostyn of Talacre


The Mostyn Baronetcy, of Talacre in the County of Flint, was created in the Baronetage of England on 28 April 1670 for Edward Mostyn. This family descends from Richard ap Hewell, who was seated at Mostyn in the reign of King Henry VIII. His son, Pyers Mostyn, of Talacre, was the great-grandfather of the first Baronet.

Charles Mostyn, son of Charles Mostyn, second son of the fifth Baronet, married Mary Lucinda (née Butler) (died 1831), a descendant of Mary, eldest sister of Henry Vaux, 5th Baron Vaux of Harrowden (on whose death in 1663 the barony fell into abeyance).

In 1838 the barony of Vaux of Harrowden was called out of abeyance in favour of their son George Charles Mostyn, who became the sixth Baron. See the Baron Vaux of Harrowden for further history of this branch of the family.

The Most Reverend Francis Mostyn, fourth son of the eighth Baronet, was Roman Catholic Archbishop of Cardiff. Sir (Joseph) David Frederick Mostyn (1928–2007), great-grandson of Captain Edward Henry Mostyn, second son of the seventh Baronet, was a General in the Royal Green Jackets.

The family sold the Talacre estate in 1919.
