Last month a baby in Tennessee made history: Emilia Maria Jesty was the first child born in the state to have a woman listed on the birth certificate as her "father."
The marital status of the baby's parents was the subject of a flurry of court filings up to a few days before her birth. Valeria Tanco and Sophy Jesty were wed in New York, a state that recognizes gay marriage, and moved to Tennessee, which does not.
They are among scores of same-sex couples who, working with advocacy groups, have filed lawsuits to expand gay-marriage rights following a major U.S. Supreme Court decision last June allowing federal tax and other benefits for same-sex married couples.
Depending on the pace of rulings, as early as next year Tanco and Jesty's case or a similar challenge could reach the Supreme Court. Since the court's June decision in U.S. v. Windsor, about 50 such cases have been filed, in nearly all 33 states that prohibit gay marriage.
