Henry Layton I
Henry (1749-1805) was the nth Baron Loseley (they've really lost track) of Loseley Park in Berkshire. He married Miss Louisa Barnet in 1780 with whom he had three children: Catherine, Henry and Phoebe.
Lord Loseley was a Cambridge graduate, a fine linguist, was friends with Important People In Government and made regular trips to France. Whether any of these things were connected or not is a mystery but at any rate, he was created first Earl Parry in 1791 for his services to the state.
Lord Loseley was stabbed to death in a random attack in Calais in 1805. The killer was not caught.
