Gary,
James Anderson & Janet McDonald are on the 1851 census at Knockinnan, Latheron; then in 1861 they are at 48 North Frederick St, Glasgow. By this time, James is 63, a tailor, and Janet is 62. In 1971, Janet, 75, is head of the house at 7 Ronald St, Glasgow. Apparently James has died.
Janet died in 1876, aged 84. Her parents were William McDonald, a Mason, & Janet Fraser.
The thread is really about Wm & Mary Stoddart. I could give you fuller details about the above if you contacted me privately.
