As to Hebrew and English name equivalents of Eastern European given names,
first realize that when a person had two given names (Example:
Froim-Menashe) the second name was his everyday name (name by which he was
known) and the first name was his religious name (shem kodesh).
So Froim_Menashe was known in life as Menashe and would have chosen as his
English name some "M" name such as Max.
Manil (some "M" name)
Mordko (Mordechai, or other "M' name such as Max, Morris)
Jos (Joe, Joseph)
Shmul (Sam, Samuel)
Pinkhas (Paul, Peter, etc.)
Zislya (not sure)
