Gattie 29.4.1799 at G's head with Suett, Sedgwick &c
If Suett and possibly Sedgwick were actors, Henry Gattie DNB 1774-1844 would be in context, but according to the DNB he made his debut as an actor at Bath in 1807. William Gattie of Brompton Row Middlesex will PCC 1814 had a perfumers and combmakers business. See also my entry for Gatty
