Found this in 1881. Not sure if it's any use?
Residence: 27 Lower Craigs, Stirling, Stirlingshire
John Kennedy, m, head, 34, painter house, Stirling
James ", m, son, 12, scholar, Stirling
There's a possible for young James in 1891 (aged 19, however) in Glasgow, lodging with the McRae family and he's a house painter. John is back in Stirling (44, house painter) with wife Janet (born c. 1843 in Tullibody, Clackmannanshire).
Only possible birth on the IGI that I can see is John Kennedy, born 25th August 1870 in Stirling. Parents John Kennedy and Janet Geoch.
