I have cross-referenced this list against the 1770 census and include that information here. They were also published in PANS 1934 Annual Report . The Irish place names are spelled the same as in the newspaper announcement. There were two men named John Mahon, living as neighbors. There was a John Barnhill enumerated in Londonderry and another in Onslow.
Further research is required to determine if they are from the above group of Irish immigrants.
In 1767-68, he moved to Londonderry, MS, and served as a representative in the assembly as of 1770. Recent reprints of both of these books are available. It is not clear what happened to the John Morrison from the above passenger list. It is possible that he may have left Nova Scotia, as apparently did many of his fellow passengers.
