In the run-up to marriage, many couples, particularly those of a more progressive bent, will encounter a problem: What is to be done about the last name? Some have attempted work-arounds: the Smiths and Taylors who have become Smith-Taylors, Taylor-Smiths, or—more creative—Smilors. But there just isn’t always a good, fair option. (While many straight couples fall back on the option of a woman taking her husband’s last name, same-sex couples have no analogous default.)
