Hi my name is Robyn Rawles (nee Devlin ) living in New Zealand. I am descended from Francis Devlin seniors brother, Henry (c1807-1895). In 1851 Ayrshire Scotland's census for West Kilbride Henry (39) and Margaret his wife are living in Meadowfoot Row with children Henry (11), Margaret (8), Patrick Lovell or Lavell (23) son-in-law, Mary (24), dau. On Henry seniors marriage (his third) to Sarah Carruthers his parents are given as John Devlin, schoolmaster, and Mary Devlin (nee Dickson). I can't lay my hands on it at the moment but I'm sure Francis' parents are the same on the death register. In 1851 Francis (19) is also living in West Kilbride with his wife Elizabeth at the Mcglouchlan's his in-laws. Hope this is of some use to you. I have a lot more info on the family including living relations in Greenock and Gourock Renfrewshire Scotland.
