I have a mystery of sorts. Mary SYMINGTON b 1821 Humbie, married Alexander COCKBURN in Dec 1847 Mid Crichton. Her sister Elizabeth b 1818 had a son to an Alexander COCKBURN about 1853 in Stow, Easterton or Lauderdale (all are given at different times on the census returns). I have not found a birth registration or a marriage entry for Elizabeth but on the marriage of the son in Crichton, Edinburgh, in 1875 Elizabeth is given as married to Alexander COCKBURN. The earlier couple Mary and Alexander COCKBURN are still living together in 1871. Any suggestions or help would be appreciated. Margaret Jenkin Christchurch NZ
