How do you properly pluralize French last names in English especially names that end in a silent X such as Lacroix?

Answer 1

French last names undergo no change when written in the plural. When speaking of the Sarkozy family as a group, you would say 'les Sarkozy' without adding any plural mark like the 's'. Speaking about the Lacroix family, you would write 'les Lacroix' and left the name unchanged - even in its pronounciation. The use of the plural article 'les' is only hint that you think of them as a group.

Answer 2

In English, French last names like Lacroix that end in a silent X are typically pluralized by adding -es rather than -s. For example, the plural form of "Lacroix" would be "Lacroixes." This maintains the original pronunciation of the name while indicating that it refers to multiple individuals.
