Searching (for a long time!) for Robert Dalziel born probably Durisdeer 1820-1826. I can trace him until1848 but then he vanishes. I think that he married (prob between 1848 and 1851) Agnes McWhir who is listed as Daughter-in-law in the home of Robert's mother at Wallaceton Cottage, Glencairn in the 1851 census. I cannot find Robert in this census. I believe that he was alive in 1883 as he (and not his children) was a beneficiary in his mother's estate.
Can anyone break this brick wall please?!?!
