My Lally ancestor is James Lally who was born in 1796 in Ireland and is listed in the 1851 British Census as a schoolmaster living in Manchester. By 1861 James is still living in Manchester and working as a hatter or hat dealer.
One of James' daughters, ANNIE, lists herself in 1891 as born in County Mayo. In 1901 she is listed as born in Castleton, Ireland.
I have looked on the various websites for Mayo and can identify Castlebar. Does anyone know if there is a Castleton in Mayo or is it more likely that the enumerator mis-heard?
