Thomas Johnes

Thomas Johnes (died c. 1734) of Llanfair Clydogau, Cardiganshire and Dolau Cothi, Carmarthenshire, was a Welsh Whig politician who sat in the House of Commons from 1713 to 1715.

Johnes was the only surviving son of Thomas Johnes of Llanfair, Cardiganshire, and his wife Anne Lloyd, daughter of David Lloyd of Crymlyn, Monmouthshire. He succeeded to his father's estates in about 1698. He married Jane Herbert, daughter of William Herbert of Hafod Uchdryd, Llanfihangel-y-Creuddyn, Cardiganshire and then as his second wife, Blanche Van, daughter of David Van of Llanwern, Monmouthshire.

Johnes died in 1734 without issue by either wife and nominated as his heir Thomas Johnes of Pen-y-bont, Radnorshire, a first cousin once removed.
