Somerville Alderman Maryann Heuston announced her candidacy for South Middlesex County Registry of Deeds, she said in a statement.
Eugene C. Brune, who is stepping down after 24 years in office, has endorsed Heuston in her bid to replace him. Brune was mayor of Somerville from 1980 to 1989.
Heuston, who represents Ward 2 on the Somerville board, has also won the support of state Representatives Tim Toomey, Denise Provost, and Carl Sciortino, in addition to nine of 10 aldermen colleagues in Somerville.
Heuston said that through her dozen years as aldermen, and three decades as an administrator for major health care systems, she is ready to take on the responsibility of higher office.
“My background is uniquely suited to the position of Register of Deeds. Strong administrative and financial experience is crucial to maintaining quality of service for the largest and busiest land records office in New England,” Heuston said.
The southern district of Middlesex County encompasses 44 cities and towns. Based in Cambridge, the registry is responsible for keeping records of land use in the district.
The primary is scheduled for Sept. 6.
