I just ran across this board and wanted to introduce myself. I am the Grandson of James Glackin. He was born in Scotland of Irish parents at the turn of the century. He was the oldest of of the family. He migrated here in the 1920's or thereabouts. He and several brothers and sisters settled int he New York New Jersy area. He is still survived by 2 brothers. Thomas (Tommy) Glackin of Elizabeth NJ and Patrick (Packy) Glackin in County Donegal (Town of Mah uh ree - that is how it sounds, I do not know the spelling.) I do know that many of the Glackins in the New York City Area and related clans - Bonners for one. As to Far Rockaway Glackins, I believe these are related to my family and while I know few details, several of my relatives may know more of this since they grew up in the rockaways.
I will gladly provide more info at a later date.

FYI My clan holds a annual reunion every fathers day in Northern New Jersey.
I am also aware of a very old clan of Glackins in the Delaware/Maryland/lower Pennsylvannia Area. I believe that they date back to early settlers of the area. They also hold an annual meeting and from comments made by one of my aunts, have an ancestoral document that has been kept updated.
All the time I have for now.
