Records of family lineages often gather large households together by placing the family name at the conclusion of a long list of descendants. In this specific record, the individuals Michael, Ishpah, and Joha are identified as members of the family of Beriah [ביאור שטיינזלץ].
However, this family label covers much more than just these final three men. The designation is meant to be applied backward, gathering a larger list of previously mentioned names into one connected household. The entire preceding group of men, beginning with Ahio, shares this same heritage and is united under the family line of Beriah [מצודת דוד].
