Jimchelsea,
Reading what I have just written and posted sounds a bit disjointed with the mention of Glenwhirry thrown into the discussion, so I will clarify.
The history I have is limited but here goes:
David O'Hara was the second son of Henry O'Hara and Jane McCurley and was born in 1863 in Ballenrin. He emigrated to NZ in the 1880's with two of his brothers.
HIs parents, Henry O'Hara and Jane McCurley of Glenwhirry, Country Antrim, their children were John, David, James, Mary Jane, Isabella Ann, Hugh and William, the children all born between 1861/2 to 1873.
I had given up on finding any more about them until I saw the mention of the migration of a branch of O'Hara's to the glens of Antrim and settling in Crebilly. When I googled the family in Crebilly, I noticed a repetition of the names of Hugh and Henry right through the history and am hoping I can link these ones here in NZ to those in Crebilly.
If the link exists it would be nice to find it.
