From the official genealogy cite of Clan Munro USA:
"Historical research suggested that William Munroe (b. 1625) was one of Robert Munro of Aldie's sons and the unknown "Munrow" listed as a prisoner of war on the "John and Sara" ship (1652). However Y-DNA research performed in 2018 (reported by Mark E. Monroe) does not verify this assumption, so we are removing Robert Munro of Aldie and Elizabeth Johnson as his parents in this database.
(Note by Betti J. Steele MD, 28 May 2019)"
This profile does not address the Y-DNA research reported by Clan Munro.
