Hi,
My GGG/F was Master of the Snow 'Rapid', 133 tons, bound from Liverpool to Alexandria, Egypt in July 1837 with a crew of 6 - Master, Mate, 3 Seaman and a Cook.
In April 1838 he signed on another Snow, Blackaller', 137 tons, bound Aracati, NE Brazil with 8 crew - Master, Mate, 4 Seaman, an Apprentice and a Cook.
Hope this answers your question.
Regards
