The plurals of names in English usually follow the following rules: 1 Names ending in-s, -es, or-sh usually have a-s or-es ending in the plurals. For example, the plurals of Python were Pythons. 2 Names ending in-ness usually have a-ness ending in the plurals. For example, the word Elon Musk in the plurals is Elon Musks. 3 Names ending in-tion usually have a-tion ending in the plurals. For example, the word Alex Jones is Alex Joneses. It is important to note that the plurals of some names may differ slightly from language to language or culture. For example, in German, names ending with the word king (-er) would usually be converted to-ings.
