I have a feeling this James may be from another branch of the family; my direct ancestor (James) left Kilbirnie around 1850, moving firstly to Lochwinnoch and later to Glasgow. There were quite a number of Barclays in Kilbirnie.
(The Rootsweb post that Sandra linked to above was made by me a good many years back.)
My Hay family weren't from Ayrshire, but from Perthshire, and the link is by marriage.
