|You might try to contact Bill Calder of Perthshire, Scotland, United Kingdom. He seems to have info on Abigail Ferguson and James Calder.|
He has a tree on Ancestry. This is the only contact info I have on him. His tree doesn't state the info you're looking for.
Or you can send me your email address and I will pass it on to him through Ancestry. Can't guarantee he'll contact you but it's worth a try.
