MILWAUKEE (AP) — One of the couples at the forefront of efforts to overturn Wisconsin’s gay marriage ban is fighting a new legal battle. The Milwaukee area parents want both of their names on their daughter’s birth certificate. Kami Young gave birth to the couple’s child, Olyvia, last year after getting pregnant with donated sperm. Young’s name is on the birth certificate, but not the name of her partner, Karina Willes. Young says the matter is simple. She and Willes got married and had a child, so Willes should be on the birth certificate. The American Civil Liberties Union has taken the matter to a federal judge on behalf of the couple.
