Looking for Info on Elmer Leroy Steele Born IN London Ontario CA Married Margaret Weston Also Born There

Another mystery in my family tree is where this line of Steele's came from. By a marriage certificate from Elmer Leroy Steele and Margaret Weston's daughter, Alice Edna Steele, I learned they were both in London, Ontario, Canada and then at some point they came to the Michigan.

According to Elmer and Margaret's marriage certificate, his parents are Aaron Steele and Sarah M. Allen.

Would like to find out their birthplaces and parents.
