The celebrations continued with a surprise visit from Gov.Martin O'Malley, who has actively worked to get the bill passed.
"That's what One Maryland's about," O'Malley said. "It's about the dignity of every individual."

Maryland gay marriage vote: House of Delegates set to make decision
ANNAPOLIS, Md. (AP) - Maryland delegates are scheduled to take a final vote to legalize gay marriage.
Members of the House of Delegates considered a handful of amendments Friday afternoon and will convene for a final voting session at 4:30 p.m.
Republicans speculated that proponents acquired the 71-vote majority required to pass the legislation.
An amendment from Delegate Tiffany Alston, a Prince George's Democrat who previously opposed to the bill, was accepted by the members, a move opponents suggested bought her vote.
The body also added an amendment Thursday evening, altering the effective date of the bill from October to January 2013.
Delegate Wade Kach, a Republican from Baltimore County, said earlier in that day that his support of the bill was contingent the acceptance of that amendment.
