Freeman Orrin MacKay was born in December of 1906, the fourth of six children born to John William MacKay and Emma Jane Deyarmond. He is my first cousin, 3 times removed.
His death record says that he was 10 days old.
However, the 1911 Census of Nova Scotia clearly shows that he was 4 years old that year, being born in December of 1906, and therefore agrees with the headstone.
Freeman was 10 years old, and died of gastroenteritis (stomach flu). He is buried in the Burnt Hill Cemetery, Upper Burnside, Colchester County, Nova Scotia, with his parents.
