Edward and Annie were married in 1922. Their marriage record at the Philadelphia County Register of Wills may have info on the parents. At the very least it will have where he was born.
I suggest getting Edward's death certificate. If he died in Pennsylvania get it directly from the PA Div. of Vital Records. His obituary may be helpful especially if it lists any siblings. Try the Philadelphia Free Library. The Historical Society of Pennsylvania, Germantown Historical Society and perhaps the Philadelphia Family History Center may be able to find something on him.
