Thy sister by either of thy parents.

Thy sister by either of thy parents.

To wit of thy father by another wife, whom he hath taken into his house.

Either of thy mother, by another, whether a former, or a second, husband in another house and family: or, of thy father by some strange woman: for there might be some doubt in these cases.
