Antrim County I found some information that Cahoon or Calhoun are still in Lisburn and it is possible that McReavy could have been McAreavy several families live in Antrim. My grandmother's family upon arriving in Canada is registered as McReavy.
Looking for William Keyes Kelly, born 1715 in Antrim county I believe. My 5th grandfather and he Emmigrated to America in the 1740's or 50's I believe. Married to a Margaret Barnsley.
