Alan,
I've just discovered your emails re Costains and would love to know if it is possible to get a copy of the Costain family tree referred to several years ago. My mother's maiden name was Costain and her father was born in Colby. although Mum was brought up in Douglas. I've confirmed links to the Ballachrink Costains, but am sure there are numerous branches of that family which I have still to explore and I'd appreciate any help I can get.
I may have 200 or so names, but not the 900 referred to.
