Bucknor is probably Buckna which is just outside Broughshane. What denomination was John, and what was his father Matthew’s occupation?
I noted this grave inscription in Kirkinriola cemetery, which is very close to Broughshane:
ERECTED BY THOMAS GILLILAND, DUNFANE. IN MEMORY OF HIS UNCLE MATTHEW AIKEN, WHO DIED 12TH FEBRUARY 1896, AGED 83 YEARS.
