Yes, Jason Horne Francis is the stepson of Fabian Francis. 

Francis’s stepfather, Fabian, is a former AFL player who also guided Francis’s football career.

However, Francis is also a private person. Thus he has never exposed his parents’ names in public.

Similarly, Francis has kept the details of his connection to himself. So, when it comes to his family, we’d say he’s pretty private.

At the same time, the identities of Jason’s biological father and mother have yet to be discovered on the internet.
