Hannah Boyd (COURTNEY)(BANFIELD)b.1858 N. IRELAND

Hello, my name is Donna and I live in NH.
I am trying to connect to someone with my GG-Grandmother:

Hannah Boyd COURTNEY b.1858,Ballymoney, N. Ireland. Arrived US 1870.
Her married name was BANFIELD.

My GG-Grandfather was her husband, named Nicholas BANFIELD b.abt.1840, England.

Hannah and Nickolas BANFIELD lived together in Freedom PA from approx. 1875-1890? by the birth dates of their children I can locate, and the date of hannah's 2nd marriage, at which time I assume Nicholas had died.

I got this info from a document of one of their children's Delayed Birth Application.This childwas named Alexander Boyd BANFIELD b.1888.

I am inclined to think that BOYD was a family name.Does the name Hannah Boyd COURTNEY ring a bell to anyone?

Thank-you for your time and any info!
