in the household of C W and Mina Larabee: daughter: Gladys Larabee, born Jun 1907 in Ontario
No explanation for why her birth month and year are incorrect. It doesn't appear to be a case of one child born and died and another born a year later and given the same name, as her gravestone (apparently) gives her birth year as 1906. It is unfortunate, as some trees have confused her with a Gladys Larabee born in New York 17 Jun 1907 (who married Robert Amsden).
