I am a descendent of these Ayrshire families who migrated to Illinois USA about 1840-50. I have my Wylies back to Alexander Wyllie, 1775-1844, and his wife Jean Allison. Alexander died in Fullwood, Stewarton and his sons and widow went to America. I am trying to figure out which Alexander Wylie born around 1775 would be mine and would appreciate advice. My Parker ancestor is John Parker, married Joanna Calderwood 1837; again I am stuck trying to nail down my John Parker. Has anyone out there gotten much use from land records?
