Guillaume
The French form of the name Poland knows as Wilhelm, built from Germanic *wil* and *helm*: will plus protection. Barely 200 men here carry it, so meeting a Polish Guillaume would stay with you.

What Guillaume means
Where Guillaume comes from and what it has meant to the people who carry it.
Guillaume comes from two Germanic roots: wil, meaning will or desire, and helm, meaning helmet or protection. Together they read as a resolute protector, a defender whose guard is backed by firm resolve. Guillaume is the French form of the name English speakers know as William.
The name traveled with the Normans across the Channel. Guillaume le Conquérant, William the Conqueror, took the English crown in 1066. His name went with him. Centuries later the poet Guillaume Apollinaire gave it a modern literary standing in early twentieth-century Paris.
In France the name settled into ordinary life, appearing on school registers and official forms without any fuss. A Polish child might meet it first in a French lesson, printed beside the William of English class. The two forms sit side by side, one Norman, one plain English, both tracing back to the same wil and helm. Read the parts again and the meaning holds: a resolute protector, strong of will.
