Thank you so much for this information. Amazing how much you have discovered. I am very grateful. I will definitely try and follow this up at Maritime Museum.
In answer to your question I am interested in a James Massey who married Betsy Cornthwaite in 1809 from Kendall and lived on Edmund Street according to 1820 baptism record of his son, also called James Massey. It states James Massey was a shipwright on this record. I think this may be the same Massey mentioned in the Bannerman- Massey partnership, or more likely it is his son, born in 1820 if the dates are 1850s/60s for the shipping info. I am assuming Bannerman must have been a business partner rather than a relative.
