Apparently, Laurell's lack of understanding in the area of proper relationship terms is contagious. The Anita Blake Compendium has this to say:
When Anita's father remarried 8 years later (based on Christmas gift of lavender blouse Anita got from Judith not returned, while her 8 gifts given to her stepmother have been), it was to a blonde haired, blue eyed woman named Judith. She had two children with him, giving Anita stepsiblings - Andria and Josh.
So apparently either Anita's father is not her actual father. Thus, the children he had with his 2nd wife are Anita's step-siblings. Or... he is not really their father at all and Judith was having an affair.

Someone's birth certificate is lying.
