Question

I will be saying Kadish at the unveiling of my father's gravestone. Besides, Kadish, what other components of the ceremony are prescribed or recommended.

Answer

The custom is to recite Psalms according to the Hebrew name of the deceased. If you open to chapter 119, you will see that it is comprised of many short paragraphs according to the order of the Aleph-Bet.

For example, if the deceased's name was Moshe (spelled Mem, Shin, Hey), then one recites the entire paragraph beginning with the letter MEM, then the paragraph of SHIN, then HEY.

Afterwards, the same thing is done, but this time according to the Hebrew word for soul - "neshama" - NOON, SHIN, MEM, HEY.

If a minyan is present, then the one who is reciting kaddish on behalf of the deceased would recite kaddish at this point. Is anyone actually saying kaddish for your mother-in-law on a daily basis? It is important to arrange that for her; we even have a service in Jerusalem whereby yeshiva students do so at the Western Wall.

Finally, it is not necessary to serve any food. Though if it is convenient for people to come to your house afterward, you could provide some snack food.

May the Almighty grant an elevation to the soul of your beloved father.
