I would appreciate a translation of the Hebrew from this stone. I'm
particularly interested in his father's name.

"Our dear father Menachem Mendel son of Yehoshua, died aged 52 on the 10th of Adar A 5681"
This is an educated 'guess' since the date isn't clear the way you typed it.  It is best to post a good photo of the stone so that we may be sure.
Also, IMHO מנדיג should be מנדיל.

I agree with Steve, and would add: it's best to post the image to Viewmate.

Inserting the Gregorian date into Hebcal Converter gives the following Hebrew date:

•  

• Tue, 15 February 1921 = 7th of Adar I, 5681

• ז׳ בַּאֲדָר א׳ תרפ״א

I agree that "Mendel" has been misspelled as Mendig.

I also agree that the date is unclear.  I suspect that the exact date in Adar appears before the word Adar.

If you have a photo, you can post it on the ViewMate page of jewishgen:  https://www.jewishgen.org/ViewMate/

Judging by the secular date of 2/17/21 looks like date should be 9 Adar 1. But the Hebrew day doesn’t match the letters we are given until we realize that Jewish days begin at sunset. 

thus I posit the date is 10 Adar 1, using all the letters in the garbled hebrew that was supplied:  י אדר א

The reasoning behind my 'educated guess' above is exactly David Dubin's reasoning. :)
