My husband is a descendant of James Aird and Mary Aitken. James and Mary's son James b. 1835 married Mary Ann Beattie in1858. One of their children, John, b. 1867, emigrated to Australia with older brother, Andrew. Both married in Eidsvold, Queensland, Australia. Andrew returned to Scotland with wife and children some years later. John (Jock) Aird and wife Bertha Schmoker had 9 children in Australia. Anyone wanting more info on this family, or copy of photo I took of James Aird and Mary Aitken's grave in Sorn graveyard can contact me. James and Mary appear in the 1851 Census of the UK. He is recorded as a farmer 0f 30 acres, residing at 16 Barrshouse,(probably as a tenant farmer).
