Thomas Aitken's father was Thomas Aitken, but that's all I know about him so far. His mother, however, was Jean Allan, baptised 1799 St Monans - and guess what, she's another of the same Allans!
The guy in Canada is Bill Burland. I'll mail him with your details and Allan links and I'm sure he'll be in touch. I've found both Janet and Euphemia Allan on the details Bill sent me, so I can provide details there in due course should there be a problem, but I'm still putting it all together so couldn't really do so right now.
You can understand why families sailed together, but disasters like that were all too common. As a boy I used to go out with Dad, with my older brother crewing. I never appreciated at the time the worry it was for Mum. My brother then had both his sons on his boat for a while at which point I was old enough to understand.
