half sister

Her half-sister Lorna Luft is, but is anyone making sure Liza's not near open flame or an exposed electronic cable?

I also had a daughter and son-in-law who were about the age of her half-brother and half-sister.

There's your half-sister's children at home; but of what use to me is a girl or a blind boy?

We made our way to a half-sister of my father's who lived in Puerto Principe, and at first—she would not have me.
