How do you write the plural of a last name ending in -ch?

For instance, Koch? Is it Kochs, or is it Koches? I thought that you added -es to all nouns ending in -ch to pluralize them, including proper nouns. My roommate, however, says that I'm wrong. Which way is correct?

How do you write the plural of a last name ending in -ch?
Kochs. Mainly because it is a name of German origin.





The rule for surname plurals is that names that end in ch, x, s or s sounds require “es” for the plural. However, “Munch” is pronounced with a k-like sound, not ch. (Moonk) so only an s is added.








Plurals with surnames: Do not change the original spelling of a surname when forming the plural. Add “s” or “es”. For example:





Singular: Mr.%26amp; Mrs. McCarthy


Plural: Mr. %26amp; Mrs. Mcarthys





Singular: Mr. %26amp; Mrs. Bartino


Plural: Mr. %26amp; Mrs. Bartinos





Singular: Mr. %26amp; Mrs. Barnes


Plural: Mr. %26amp; Mrs. Barneses

Reply:If the "ch" sounds like "K", you just add "S" to make "Kochs". If it sounds like the "ch" in "chicken", you add "es" to make "Koches". Never add an apostrophe to a plural noun.
