Name: Alan Jackson
Played by: Joseph Millson
Home Planet: Earth
Species: Human
First Appearance: Invasion of the Bane (2007)
More Information: Alan is Maria's sympathetic, caring and very understanding father. He has a brilliant easy going and casual relationship with Maria, which Sarah Jane would love to emulate with Luke. That doesn't mean he doesn't still do embarrassing dad stuff though. The odd ruffle of Maria's hair and insistence on a goodbye peck on the cheek before school, is enough to make anyone cringe. Working in the IT industry and recently divorced from Maria's mum, Alan lives a pretty suburban life.

Name: Chrissie Jackson
Played by: Juliet Cowan
Home Planet: Earth
Species: Human
First Appearance: Invasion of the Bane (2007)
More Information: Chrissie is Maria's warm hearted, but flighty mother. Although divorced from Alan and living with her boyfriend Ivan, Chrissie still makes regular visits to see her daughter and it's obvious that she loves her to bits. Maria misses having her mum around, but she finds her a bit trying at times. Chrissie's ability to speak before thinking, and usually at a hundred miles an hour, makes her seem just a teeny bit self obsessed and rude to almost everyone she meets, including Sally Jane, Mary Jane or whatever her name is. She never means any harm though, she's just...Chrissie.
