Hi namma
The marriage of James & Isabella is readily accessible on Scotland's People.
http://www.scotlandspeople.gov.uk/It's free to register, then free to search (up to a point)) then a very reasonable rate to purchase the BDM certificates online. The Marriage I found (see below) is from a free Index search.
