DENVER (AP) — Denver and Boulder both began issuing civil union licenses just as a new law authorizing them took effect in Colorado at 12:01 a.m. Wednesday.

The first gay couples granted civil unions in Denver said their vows before hundreds of people early Wednesday morning at a downtown municipal building.

The Denver Clerk and Recorder's Office said 130 couples checked in before Wednesday morning's 3 a.m. deadline. The office resumed issuing civil union licenses at 8 a.m.

In Boulder, 48 couples entered into civil unions overnight.

The Daily Camera reports that the first couple in line was Bonnie Lloyd and Pattea Carpenter. Their attorney says they were also the first lesbian couple in the United States to have both of their names placed on their child's birth certificate.
