The 1881 census lists Martha Greig as family head residing at 52 Kemback Street Dundee with children John (14) Jane (10) Duncan (8) (my grandfather) Barbara (6) and Isabella Greig (1). Noticibly James (Martha's husband) in the 1871 census (and their son James) are not listed. At this stage I have been unable to locate any information on James snr and son on their demise.
