Hi aghadowey
That is really a good site.
It was very interesting.
I looked through all the names of Halliday.
There are a few John Halliday’s in that site.
There was a John & Henry Halliday of the parish of Kilkeel
It had “in Ballinture; named on a freehold lease of John Rogers, farmer as having a life interest 1819”
There was also
John Halliday of Kilkeel “will dated 1788”
John Halliday of Kilkeel “will probated in 1837”
also
John Halliday of Drumgooland “of Ballyward; will dated 1833”
The Ann Hallidays in the list were born after my Ann and there is no reference to marriage to Ann Parkhill and no mention of Ann Parkhill at all.
I looked up Parkhill and there were two. Both men.
John Parkhill “emigrated to Philadelphia on 'Prosperity' Jun 1775”
James Stilwell Parkhill married in 1922
So no luck there.
It was worth a try and maybe a link can be made.
