Hi Paul,
John and Janet farmed at Bograxie, near Inverurie, from about 1852 till 1881 when they seemed to disappear. I haven't investigated emmigration possibilities yet. Their son James, born Insch 1849, was also farming at Bograxie in 1881. He died in 1885, found drowned in the well of a neighbouring farm; his widow and family were at Newhills near Aberdeen in 1891. Keep looking and maybe we can finish the jigsaw one day.
John.
