Don't believe that I can be of help. My wife is a Mannix. Her father and other siblings came to USA in mid 1920's. Family info, back to late 1700's depicts group from Charleville, co. Cork, Ire. My wife's great uncle was Archbishop Daniel Mannix , former Director of Maynooth, and later archbishop of Melbourne Australia. He, Daniel 1864-1963, had quite a history. The family however is well documented through Co. Cork. We have no record identified for upstate NY.
