Hi Dean
You may know this by now. Killead is a small village beside Belfast International Airport, Aldergrove. You will find Killead Road on Google Maps. Mill Farm is probably just that the name of a farm but you could try this website fro more info.
www.glenavyhistory.com/killead_presbyterian_church.html I have a mystery to sort out in the search for ancestors which concerns a Captain John Mcelrath. I wonder if you might have some clues for me.
Captain John Mcelrath is named on marriage entry for Robert Orr (His son,1848-1888) and Eliza Young in Dundonald Co Down 1866.
We always thought our Orr family came from Scotland in 1600's and were in Antrim area in 1700's and then moved to East Belfast. Dundonald would be in present day East Belfast.
I cannot make the Melrath connection and therefore cannot take my search any further.
Have you information which you are willing to share?
Incidentally I found another as yet unverified, Mcelroth reference in Dundonald which has military and American connections.

Lieut. Colonel Robert McLeroth late of the 57th regt. He entered His Majesty’s service in 1769, his promotion – his merit; alone he served in the American War, was a brave and popular officer a benevolent and kind brother uncle and friend to all his relatives he died 26th March 1805 in the sixty-fifth year of his age regretted by all his acquaintances and Freinds.
Hope I have been of some help and you willing to reciprocate,"
