This John Keillor was born in Amherst, N.S. c 1789 son of Thomas Keillor and Mary Trenholm. I want to know who his twin brother was and any sources there are. John married Nancy but not sure if she was Haywood or Hayward. Second wife Sarah Betts. John died in 1860 Dunwich twsp. and is buried Yarmouth Baptist Cemetery but there is no stone.Not listed in probate unless it is found with land records. Any info will be helpful.
