Margaret Drury, Cambridge’s city clerk since 1992.

Margaret Drury, Cambridge’s city clerk, confirmed Monday after a short City Council meeting that she does intend to retire early next year, with February likely to be her final month of work.

Drury, a graduate of the Suffolk University School of Law, has been city clerk since 1992. She has spoken of officiating at the nation’s first same-sex marriage ceremony — shortly after midnight May 17, 2004 — as being a highlight of her 19 years in office. She joined a clerks’ lawsuit that year asking the state to let nonresident gay couples also marry in Massachusetts, a right that was granted in 2006.

Her official notice hasn’t been given, she said.

Resident Charles Teague said he’s known of the retirement, from Drury, since the summer, and that a replacement was expected from among her staff of 10, many of whom — including Deputy City Clerk Donna Lopez — have also served for many years.

In December, councillor Craig Kelley suggested looking at the repercussions of retirements among high-level staff such as the city clerk and city manager. The motion, swamped under charges it verged on age discrimination, never took place.

The city clerk is the official record keeper for the city, and records kept by her office include vital statistics such as birth, marriage, domestic partnerships and death and business and professional certificates, the city website says. The clerk is also the official keeper of the city seal and city ordinances.
