Old Parish Records from Berwickshire show that Alexander Falconer and Helen Brown had the following children: John (b. 1781 in Duns), William (b. 1783 in Duns), James (b. 1790 in Bunkle and Preston), Alexander (b. 1793 in Bunkle and Preston), Thomas(b. 1795 in Bunkle and Preston), David (b. 1798 in Duns), and Margaret (b. 1801 in Duns). I suspect (without proof) that Alexander was born in 1753, the son of John Falconer and Margaret Hay in Yester, East Lothian. There was a George Falconer, married to Beatrice Mack, who was having children between 1783 and 1794 in Berwickshire, who I suspect was a brother of Alexander, born also in Yester in 1751. Both Alexander and George had children named John and Margaret.
