2.  Distributing Mishnayos for the Shloshim:

It is a great merit for the soul of the deceased when others study Torah in its merit. For this reason, it is customary to divide the study of all the tractates of the Mishnah amongst friends and family, completing it by the Shloshim.  

Whose name do you mention-the father or the mother:[1] When learning Mishnayos in memory of the deceased, one is to mention the name of the father.
