In addition to Deb Mell, the applicants were identified as: Robert F. Elrick; Elizabeth Lynn Gomez; Gretchen Carol Helmreich; Jonathan Andrew Markel; Mallen Elizabeth Pittman-Fernandez; Grace Trocollo Rink; Edmund Joseph Sieracki; Matthew Boyd Terry; Andrew Amador Tinajero; Annisa Michele Wanat and Sergiusz Piotr Zgrzebski.
A "blue ribbon" committee is responsible for selecting the top candidates for the job, then Mayor Rahm Emanuel will select Ald. Mell's replacement.
The Sun-Times reports Deb Mell is the odds-on favorite.
If selected, Deb Mell, 44, would be the third openly LGBT alderman in Chicago, after Alds. Tom Tunney and James Cappleman. In 2010, Mell and her partner, Christin Baker, were married in Iowa.
Emanuel is expected to install a new alderman at the July 24 City Council meeting.
