Powerscourt was the son of Richard Wingfield, 5th Viscount Powerscourt, and Frances Theodosia, daughter of Robert Jocelyn, 2nd Earl of Roden. Through the Wingfield line he was a descendant of the Noble House of Stratford.[1] After the death of his mother in 1820, his father remarried Theodosia Howard, who raised him until he succeeded to his father's title 1823.[2]
Powerscourt succeeded his father in the viscountcy in 1823. However, as this was an Irish peerage it did not entitle him to a seat in the House of Lords. He was instead elected to the House of Commons for Bath in 1837, a seat he held until 1841.
Lord Powerscourt married his first cousin Lady Elizabeth Frances Charlotte, daughter of Robert Jocelyn, 3rd Earl of Roden, in 1836. They had three sons.[3] He died in August 1844, aged 29,[4] and was succeeded in the viscountcy by his son Mervyn, a great-great-grandfather of Sarah, Duchess of York. Lady Powerscourt married Frederick Stewart, 4th Marquess of Londonderry, in 1846.[5]
