I realise this thread is just over two years old and Josh Swann has not been active since.
However today I went for a walk in Bank Woods and found the remains of the cottage I believe is the Bank referred to on the old maps. The ruins are certainly in the exact location.
I have taken some photos which I would be happy to post if Josh is interested - hoping he recieves an email alert ( fingers crossed)
Looby 
I also share this ancestry with Josh and have found this thread interesting. I had followed the Allan’s of Galston, Riccarton, Craigie until they emigrated to Australia, where I am from. Out of coincidence I now live in Ayrshire with my Scottish wife.
If you do have bank woods photos of ruins I would be interested to see these if you still have them.
