This is Jane DUNCAN (nee HEATLIE) son: Walter Davidson DUNCAN
He moved about a bit!

1871: Garlshore? Siddings? Colttage, Kirkintilloch, Dumbartonshire
Head: Walter D DUNCAN 36, ----? Man, (Gentleman?) b Ancrum Roxb.
with wife Margaret 33, ----ntemans wife? b Glasgow & 7 children:
Alexander- 12, Grace S-10, George M -8 , b Arbroath, Forfar
Jane H - 6, Walter G - 4, Robert M - 3, William G - 1mth, b Kirkintilloch
Note: Eldest son and 2nd eldest daughter on the 1871 Census are named: Alexander and Jane H DUNCAN (fits naming pattern). Dau Jane's birthplace appears to be incorrect as the IGI have it in Lanarkshire (below). Perhaps she was born at the home of her mother's folks but they lived at or were shortly afterwards at, Kirkintilloch. Occupation of 'Gentleman' for Walter, if that is correct - hmm, combined with the moving about, appears to be in reduced circumstance in 1881 below ....he may have been a bit of an 'entrepeneur' type ?1881: Parkfoot, Kilsyth, Stirlingshire
Head; Walter DUNCAN 46, General Labourer, b St Boswells, Roxb.
Dau: Grace DUNCAN 20, Domestic Servant, b Abroath, Forfar
Son: Walter DUNCAN 15, Apprentice Blacksmith, b Kirkintilloch, Dunb.
