Her name was Sarah Taylor; her parents were Richard and Elizabeth Taylor.
Her family is on the 1841 Scottish census with just one child, John, then again on the 1851 census with 3 children - John, Elizabeth and Sarah.
Sarah is back in England in subsequent censuses and her details suggest a YOB around 1844 -5, (not 1843, sorry!), birthplace Old Monklands.
I've no idea whether or not she was baptised in Scotland; if she was, it would have been in an Anglican church of some persuasion.
