James Gettys b. 1816 & Eliza Jane Agnew from Co. Antrim

I have tried for years to locate information on James Gettys (1816-1876)and his wife Eliza Jane Agnew (1815?).I do not know where they were born in Co. Antrim or if they were married there.They lived in upstate N.Y. early in the 1840s until their deaths.I would appreciate any information on where they came from in Antrim and/or who their parents and siblings were.

Thanks for your help.
