I think I have found out info on my grandfather's side of the family back to mid 1700, if it is correct.
His parents were William LAING b1831 & Elspet MCHARDY 1838, they had 6 children, my grandfather James had a twin sister, Jessie. William's parents were JOHN LAING 1797 & ELSPET COBBAN 1800?? both from SANDYMOSS, DUFFUS, Moray.
I found LIBINDEX for Morayshire very helpful, & it is free. Also Scotland's people but it is a pay for use site. I do not know if any of the Laings, Bartletts or Jeffreys still live in the area or not. My grandparents left Scotland in the early 1900s to homestead in HARRIS, Saskatchewan, Canada and are both buried in Canada.
