Turns out that “Miller” comes from the profession of milling!
OK, that was obvious, but if you are a fellow Jew with a more interesting last name, this is a cool article by Bennett Muraskin in Business Insider:
Ashkenazic Jews were among the last Europeans to take family names. Some German-speaking Jews took last names as early as the 17th century, but the overwhelming majority of Jews lived in Eastern Europe and did not take last names until compelled to do so. The process began in the Austro-Hungarian Empire in 1787 and ended in Czarist Russia in 1844.
In attempting to build modern nation-states, the authorities insisted that Jews take last names so that they could be taxed, drafted, and educated (in that order of importance). For centuries, Jewish communal leaders were responsible for collecting taxes from the Jewish population on behalf of the government, and in some cases were responsible for filling draft quotas. Education was traditionally an internal Jewish affair.
Until this period, Jewish names generally changed with every generation. For example, if Moses son of Mendel (Moyshe ben Mendel) married Sarah daughter of Rebecca (Sara bat rivka), and they had a boy and named it Samuel (Shmuel), the child would be called Shmuel ben Moyshe. If they had a girl and named her Feygele, she would be called Feygele bas Sora.
Jews distrusted the authorities and resisted the new requirement. Although they were forced to take last names, at first they were used only for official purposes. Among themselves, they kept their traditional names. Over time, Jews accepted the new last names, which were essential as Jews sought to advance within the broader society and as the shtetles were transformed or Jews left them for big cities.
The easiest way for Jews to assume an official last name was to adapt the name they already had, making it permanent. This explains the use of “patronymics” and “matronymics.”
PATRONYMICS (son of …)
In Yiddish or German, “son” would be denoted by “son” or “sohn” or “er.” In most Slavic languages, like Polish or Russian, it would be “wich” or “witz.”
For example: The son of Mendel took the last name Mendelsohn; the son of Abraham became Abramson or Avromovitch; the son of Menashe became Manishewitz; the son of Itzhak became Itskowitz; the son of Berl took the name Berliner; the son of Kesl took the name Kessler, etc.
MATRONYMICS (daughter of …)
Reflecting the prominence of Jewish women in business, some families made last names out of women’s first names: Chaiken — son of Chaikeh; Edelman — husband of Edel; Gittelman — husband of Gitl; Glick or Gluck — may derive from Glickl, a popular woman’s name as in the famous “Glickl of Hameln,” whose memoirs, written around 1690, are an early example of Yiddish literature.
Gold/Goldman/Gulden may derived from Golda; Malkov from Malke; Perlman — husband of Perl; Rivken — may derive from Rivke; Soronsohn—son of Sarah.
