It is likely that John B Smith was a previous child. I could not find a record of this birth or that of Harriet Collins or one close. However Harriet had 10 children in the years 1875 to 1894. Given that age 20 to 40 are the main childbearing ages she would have been born around 1855ish. I could not find a marriage for them either.
