thanks for the replies

I just typed a lengthy reply and lost it all

when the page froze.. just my luck
lil growler.. the first and last links you posted I knew about, the first is my own site and the last is my research partner.. but I didnt know about the middle one and will take a look at it shortly.. thank you.

apart from Emma I only know about 3 of the sister's.. the remaining 3 (youngest) siblings probably went with their mother.
I have Ann and Arthur's marriage certificate but its very basic, not even their ages are on it.
Mare, I've heard from people here and there via my site.. thats how I've managed to find out about the marriages of the three other siblings... it has helped hugely to have a website up and running, its so exciting when you hear from somebody.
Althea.. thats very interesting. Ann had already named one of her children Ann.. but she married on the ship and was Ann James by that time.. but its not a very common surname.
I hope I've answered all the questions and not missed any, I smell my dinner cooking and its making me hungry. I will come back later when the kids are tucked up in bed.
I'm grateful the tips.
