Margaret Killey baptised 4th October 1801 German, married Hugh Kneale Knayle Kneale 1821 making her 20, her children Margaret 1822 Ellen 1828 and John my greatgreat grandfather 1833, so 1851 census she should have been 50 and her husband 55, is this any help, I have read the wills and wonder know if Margaret Killey should be Kelly maybe, as I cant see why she would be called Black when she was still with Hugh and John in 1851
