GREENVILLE — Two more same sex couples plan to ask for a marriage license at the Greenville County courthouse.

The couples are heading to the courthouse Tuesday, a day after three other couples with the Campaign for Southern Equality were denied marriage licenses at the same courthouse. After asking for the licenses, the group will hold a prayer service outside.

The couples want to bring attention to South Carolina’s ban on gay marriage, which passed in 2006 with 78 percent of the vote.

Another same sex couple plans to ask for a marriage license at the Charleston County courthouse on Thursday.

The Campaign for Southern Equality backed about 20 same-sex couples in Asheville, N.C., who also sought marriage licenses knowing they would be denied.
