Alexander Calderwood was born about 1810, I believe in Unshinagh which is in Ballymoney area or Inchinagh which is in the Finvoy area.The families over in Ireland know of the each other, they know that they are related but do not know how.I have been over there about 9 times doing research and have contacts with each line at the present.
I know that Alexander and Margaret lived at the farm house in Unshinagh, Ballymoney area.I have pictures of the house and have talked to the decendents over there about the families. John's brother was James and he is my wife's gg...granfather.We do know more about that line than John's line though.
Does the record of the marriage say that they were living in Finvoy, because the marriage took place in Dervock, which is in Derrykeighan Parrish and Ballymoney Poor Law Union.I wonder if it said the parrish that Inchinagh was in?
Good luck on your lines, if you decend from John, you are related to my wife.
