The root families on my tree include Hallenbeck,Kelsey,Green and Akins mostly from the New York Hudson Valley region.The Monaghan branch of the family originated in Ireland moved to Carlisle,England and eventually wound up in Fall River, Massachusettes.
I have traced the Hallenbecks back to Teunes who was born abt 1817 in Greenport,Columbia County NY.
The Greens go back to Merrit Elmer Green b Sept 16, 1870 in
The Kelseys go back to Thomas Kelsey b 1790 in I believe NY.
The Akins go back to John Akins b abt 1791 in Hudson, NY.
The Monaghan branch goes back to John W Monaghan b Sept 17,1842 in Enninkillen Ireland.
I would love to exchange information with any relations still around.Look forward to hearing from you.
