I am doing family research into the family of Annie Duncan-McFadyen Chalmers and Joseph Horne McKill. Annie's grand father was Alexander Chalmers' second wife Margaret Duncan. My family connection is through Alexander's first wife Mary Robinson.
Alexander's only child from his first marriage emigrated to Australia in the 1850s. Does anyone know anything about this family? We have a photograph whom we think is of Alexander's children, who lived in Aberdeen and would like to confirm this.
