This is a long shot, but during the Rev. War there were Adairs in N.J. who later went to Canada, as they were Loyalists. Among these was John (I)Adair and his wife, Phebe Mills Adair. They had children in N.J. and Canada: Abigail 1787; Mary 1789; John 1791; Hannah 1793; William 1795; Daniel 1798; David 1802; James 1803 Hiram 1805; Sarah 1807; Poebe 1811; Abraham 1812. John (I) was a son of David Adair and may have had other brothers. They lived in Delaware at the start of the war and then went to N.J.
