NB it has not yet been fully resolved which were the 'James Smith' and 'James Smith junior' shown among the partners in Leitch & Smith in 1807 and again in 1818 and 1823. James Smith of Craighead had died in 1815: the likely candidates for the later references thus appear to be James Smith (d. c. 1836), son of John Smith of Craigend, although nothing else to date has suggested he was a partner, and James Smith of Jordanhill, son of Archibald Smith of Jordanhll, and known to have been partner in the firm.
