The ballot in the race to replace former City Councillor Chuck Turner took another step towards solidifying, with city elections officials certifying six candidates, including Gov. Deval Patrick's former political director and former state Sen. Dianne Wilkerson's son.

Tito Jackson, the Patrick aide, and Cornell Mills, Wilkerson's son, gathered more than the 191 signatures needed to get on the ballot. Also on the ballot are Natalie Carithers, former aide to ex-state Rep. Willie Mae Allen, Danielle Renee Williams of Roxbury and perennial candidates Althea Garrison and Roy Owens.

The preliminary election, which will winnow the field to two candidates, is set for Feb. 15. The final election is on March 15.

Falling short were Candace Sealey, who was taking a leave of absence from U.S. Rep. Michael Capuano's campaign to run for the seat; Abdillahi "Mash" Abdirahman of Roxbury; and five others (Sheneal Parker, Anthony Baker, Lee Buckley, Charles Omekagu Williams, and James Carr.)

Candidates can request a review of the certification. Sealey fell short by six signatures, while Abdirahman fell short by twenty signatures. Parker needed 14 signatures.

Candidates on the ballot can also withdraw or have their signatures challenged, as Garrison has frequently attempted in order to knock her opponents off the ballot.

A requested review would be completed by Jan. 13.

A drawing to determine the ballot order is tentatively scheduled for Jan. 20 at 9:30 a.m. in City Hall.

Turner was removed from the City Council after he was convicted of accepting a $1,000 bribe and lying to federal agents. He is suing the city to get his seat back.

Turner's sentencing is scheduled for Jan. 25.
