(CNN) - Being gay in Chile, Andres Rosenberg Benadretti once thought he could never get married. But his family's past may help him tie the knot some day.

Spain, where same-sex marriage is legal, has been considering a law that would make it easier for Jews of Spanish descent like Rosenberg Benadretti to get dual citizenship.

"This is something that can actually happen for me – it would be a dream come true just to have the option," said the 27-year-old. "Every human being should have the option to get married."

That isn’t the only reason Rosenberg Benadretti wants a Spanish passport, though. Mainly, he wants acknowledgement of his Spanish heritage, which goes back more than five centuries.

“My ancestors would be proud of me, and if one day I get to have children of my own, I’d love to pass on this beautiful cultural baggage,” he said in an e-mail.

Centuries after Spain formally and sometimes violently prevented Jews from practicing their religion, forcing them to convert or leave the country, the proposed law would open the country's doors to the dispersed descendants of Sephardic Jews.

On June 6, the country came one step closer to correcting what one Spanish official called a 500-year-old "error."
