Hello: Some friends are getting married soon and I want to address my gift to the new couple. In English, I would say that Jane Smith and John Doe are the new Mr. and Mrs. Doe. But in Spanish, does the woman take her husband's last name when she marries? When Maria Lopez marries Juan Chavez, do they become Sr. and Sra. Chavez? Or does the woman add his name to hers to become Maria Lopez de Chavez? The custom is a little confusing and I hope someone can explain it to me. Thanks!
