Hi Lori…, a belated welcome to The Kintyre Forum.
Well, it doesn’t look as if you’re having much luck in connecting with your family.
Please may I suggest trying RootsChat.
This is an extremely interesting Forum and it has a specialist section in relation to Argyllshire. http://www.rootschat.com/forum/argyllshire/
If that doesn’t work, their ‘Common Room’ may have Campbeltonians elsewhere in the UK and they be able to help you.
Make sure to use the title ‘William Ferguson – Campbeltown’ to draw attention to your inquiry.
Yours Aye…, Iain.
