I have been looking for the name McKeague around the Dunseverick area, seems they lived mainly at Aird, although the name tends to vary on birth and death records. So far the variations that I have found are McKague/Mckeag/McKaig which is making people a little difficult to find.
So far I have this:
Father - Andrew McKeague (1818-1910)
Spouse - Elizabeth Douglas (1837-1914) meant to have been from Tonduff
Their children are are buried at Billy church but unsure if parents are there as not mentioned on gravestone:
William Hugh - died 1951
Andrew - died 1895
Alice - died 1896
Ellen Mary - died 1895
Eliza Ann - 1895
On Andrew and Elizabeth's birth record, his father is listed as Daniel.
