Once the province of Halloween season, the celebration of the supernatural has become a year-round television phenomenon. “My Ghost Story” (9 p.m., Biography) returns with personal tales of the macabre, including the legend of a hotel haunted by a Civil War colonel, a poltergeist in a morgue (where else?) and a Pennsylvania saloon “protected” by the ghost of a departed gangster. These folks not only relate their tales of apparitions, but also capture them on film and video! “My Ghost Story” is not to be confused with Biography’s “Celebrity Ghost Stories,” slated to return just in time for Halloween, at 9 p.m. Oct. 29.

• Kim Delaney (“Army Wives”) returns to the small screen in “Finding a Family” (7 p.m., Hallmark Movie Channel). Alex (Jared Abrahamson) becomes embroiled in a foster-care nightmare after his brilliant mother (Delaney) suffers an accident that leaves her reeling and subject to depression. Intelligent like his mother, Alex soon discovers that his only way out of the foster-care maze is to petition strangers to adopt him. “Family” is based on a true story; the real Alex went on to a new home and a Harvard education.
