Below are the Census records for Bell Island for 1921, 1935 and 1945. You will see that John and Leah are listed in the 1921 census as living in the same household as John's parents as she is listed as Daughter in law. They have no children as they married in May 1921. Leah passes away in 1931.
In the 1935 census John is listed with his new wife Pearl and 5 Children , 4 of which obviously from his first wife Leah and one by his new wife Pearl as per their ages in 1935 census.
In the 1945 Census John is listed as Edward J. instead of John, also with Pearl and 4 children.
As per the 1921 Census you now have John's parents names, i.e. Stephen born sept 1867 at Lance Cove and Mary J. born Jul 1869 at Freshwater.
Hope this is of some help to you. Good luck in your research.
