A Perplexing Question

From the Havre Daily News:
Lacey The Boy, 30, is being held on felony charges after a disturbance 600 block of 1st Street West Saturday morning.
Officers said they responded to several 911 calls that someone had a gun and a bat and was going after a pickup. Police they were unable to verify that a gun was shot in the incident.
By the time police had arrived at the scene, both the pickup and a gray car with the other participants, had left the scene.
But police said they eventually found both cars, and the investigation is continuing.
The Boy is being held at the Hill County Detention Center, pending charges from the Hill County attorney‘s office, Police Chief Gabe Matosich said.

So, in the The Boy family, what do they call the girls in the The Boy Family family?
