Ooooh! How lovely! I envy you both! Thoroughly enjoyed researching my mariners!
Don't know if either of you can get in to London at all, but I have to say the big dusty old ledgers that hold the new Master's names are a joy to behold if you can. I burst into tears when I first saw my 2x great grandfather's name listed there when they were held at the Guildhall library. Oh, I know it's only a ledger, but knowing that that bit of writing was contemporary with him and knowing what he'd gone through to get to that position and get his name listed there and, knowing what happened to him afterwards...I'm still choked just thinking about it.
Let us know how you get on and, if I can help looking for ships once you know them, no problem.
Regards
Ann
