mixed filiation ms.n+M jr.n+M (early date excluded)

Filiation formulae of the type ms.n+mother's name reemerge at the turn of the 13th Dynasty after having fallen out of use around the late reign of Senusret I. If both formulae ms.n+mother's name and jr.n+mother's name are occur in an inscription a late 12th - early 13th Dynasty date is likely when no indications of an earlier date exist.

late 12th Dyn. - early 13th Dyn.
