Dayton, Ohio Mayor Nan Whaley will officiate over the commitment ceremonies of six gay and lesbian couples during the city's Gay Pride festival.

Whaley, the Pride parade's grand marshal, told the Dayton Daily News: “I wish it could be a marriage ceremony.”

Whaley is a member of the 400 plus-strong Mayors for the Freedom to Marry, a group which advocates for marriage equality.

An inaugural ceremony during last year's festival included 50 couples.

“We will do it each year until marriage equality is legal in the state of Ohio,” Randy Phillips, president of the Greater Dayton LGBT Center, told the paper.

The couples will tie the knot on Courthouse Square in downtown Dayton following the parade.
