Final answer:
Frank's adopting family, with whom he lived from age one to 19, is his family of orientation, which is the family that raises an individual.
Step-by-step explanation:
When Frank lived with his adopting family from age one until he enlisted in the military at age 19, sociologists would classify this family as Frank's family of orientation. This term refers to the family into which a person grows up and is socialized, which can include biological parents, adoptive parents, guardians, or other primary caregivers. As opposed to a family of procreation, which an individual forms through marriage, the family of orientation is the one in which a person is raised.
