Sorry the obit does not give parents only she was born in Port Royal & grew up there. You would have to follow the other siblings and hope one of their obits gave the info or one of them married twice. There are a few wills at the archives in Simcoe that may help but I will not be in for at least a week.
Ps I did check the death registration but it did not mention parents and I do not have early assessments for Walsingham. And the 1828 military did not list a Spencer.
