Not sure if this is your guy, I worked backwards from a death for that name and birth year.
David Craig master hatter 74 yrs. died Oct 28, 1894 Blythwood, Glasgow widower of Helen Buchanan. Lived at 342 Argyle Street, Glasgow. Parents were William Craig-hatter deceased and Elizabeth Craig m.s. Murray deceased. Died from disease of the kidneys, dropsy. Scotlands People GROS Data # 644/07 0398
So then looking for marriage, David Craig & Helen Buchanan August 20, 1847 St. Cuthberts, Edinburgh Scotlands People GROS data#685/002 0460 0324
Not sure if these are correct but........
