Of course, Selma was raised in a Lutheran family. Sid Riley's family came to the States from England. His family was Church of England/Episcopalian until they moved to Dover. Ohio. There wasn't an Episcopalian Church in Dover at that time. They joined a Lutheran Church and Sid was confirmed a Lutheran.
At some point after their marriage, he and Selma joined "The Evangelical Lutheran Church of the Holy Trinity" (aka Holy Trinity) located on North Prospect in Akron.
