Alexander Calderwood, Killydonnelly died 6 Sept.1882
"Administration (with the Will) of the personal estate of Alexander Calderwood late of Killydonnelly County Antrim Farmer who died 6 September 1882 granted at Belfast to Matthew Calderwood of Killydonnelly Farmer the Son." Will mentions wife (still alive), sons Robert, Matthew, John & daughters Elizabeth, Mary, grandson Alexander (Mary's son), grandson Alexander (Robert's son). Can't see a date Will was written so this may explain why the estate was administered.
I can post lots more details of Alexander Calderwood's descendants if anyone interested.
