3/5/2021 - The Familysearch.org link in this profile points incorrectly to Olivia Minnie Legge, born 26 Apr 1846 at Scot's Bay, parents: Michael Legge and Ann Elizabeth Lautz. The next column lists date of marriage (of parents) as 1855, the informant being Mrs. A. E. Legge of Scot's Bay. There is also a Legge who married a Russell. But all these marriages occurred around 1850, far too late for this couple. Fetterly-28 03:44, 6 March 2021 (UTC)
