Sir John Benn Walsh, 1st Baronet (10 February 1759 – 7 June 1825) was an English landowner and MP.
In 1795 his wife inherited the India-made fortune of her mother's brother Sir John Walsh on condition that they changed the family name to Walsh, which they duly did, by Royal Licence[1][2] and that it would go her eldest son when he came of age.
[3] Benn worked for the East India Company in Benares, India as an assistant and secretary to his brother-in-law, Francis Fowke, making a small fortune in the process, which he invested in land to enlarge the family estates, making his family seat at Warfield.
[3] He served as High Sheriff of Radnorshire in 1798 [4] and sat as an MP for Bletchingley, Surrey from 1802 to 1804.
[3][5] He died in 1825 and was succeeded by his son John, the future Lord Ormathwaite.
