Here's what launched us on our journey to learn as much as possible about her: a watercolor, ca 1830, found in a local fine arts gallery. It measures 8.50 by 12.50".
We can tell by the colours she's flying that the painting dates to before 1842 when her career as a ship of the Royal Navy came to an end.
The painting shows her with three masts, whereas a brig-sloop has two. We discovered that she began, and ended, her days as a brig sloop, but had the third mast between 1825 and 1830. This fact further dates the painting.
