John Murdock Dick & relatives Co. Armagh, Ireland

After taking a break, I am back researching various families of Co. Armagh, Ireland - specifically Forkhill Parish and hoping to make contact with others, possibly connected.
In 1868 John Murdock of Shanroe, Forkhill, Co. Armagh made his will and in it he named various relatives. One was his cousin Godson John Murdock Dick who was "at Sea". I believe John Murdock Dick was a brother of Barbara (Dick) Wright and that their mother was named Ann - a sister of John Murdock who made the will.
This Murdock family connects to not just the Dick's but the Forde's (I suspect my ancestors). Would be happy to share what I know and or suspect about these lines.
