Zelma Boetcher, born Nov 1896 (age 4), born in Wisconsin
Her birth date has been transcribed as Mar 1896, but a close look at the image shows that it was written as Nov 1896 (N written differently from M in May on other lines).
She is not the daughter of her father's second wife, who had only 2 children by 1900, who are listed after her in this census (Arthur and Edward).
