Timothy White's Ancestry

Through my grandmother, I am a descendant of The Timothy White who married Weighty Porter in Nova Scotia in 1793.By some, he is said to have been born in 1767, a son of Andrew White (a descendant of Pilgrim, William White) and Sarah Reilly/Riley, and by others, it is said he was born in 1769 and was a son of Timothy White and Elizabeth Montgomery, and that he ran away from his home in Boston at the age of 20 and was never heard of again by his family. The Timothy White, who married Weighty Porter, lived in Kings County, Nova Scotia, which borders Annapolis County, and that is where the Timothy, son of Andrew White was born. Can anyone help me verify which Timothy I am descended from? Thanks for any help!
