I have a baptism for the eldest child of John Middleton and Elizabeth Taylor - Margaret Middleton October 22 1848 in Tillicoultry, Clackmannanshire. Unfortunately I can't find a marriage for John and Elizabeth. Elizabeth (born Lincolnshire c1822) wasn't in Scotland as far as I can tell in 1841, but there are too many single Elizabeth Taylors in England to narrow down the search for her ancestry. Just checking - might the parish register have more details on John and Elizabeth? The couple were in Selkirk by 1851 and all censuses until last one only show birthplace as 'England' for Elizabeth.
