Over the last week, I have posted an number of Email about the 1718 migration form Northern Ireland to Boston, MASS. who them moved onto New Hampshire. It does raise the question of if there were any other "organised" migration after this period. I do not know enough about the local History of County Londonderry or Northern Ireland to know when such migrations may have taken place. >From the Boyd migrations to the USA from Northern Ireland families there would appear to be Migrations in:- 1720's; 1736; 1750 and 1770-1772 I know that in this last period the Flax crop in Northern Ireland has failed, so that would most likely be the reason for this later period. Do members of either list have or know when other migrations may have taken place form Northern Ireland and for what reason? Thank you Mike Boyd Historical Committee, HBS
