Last names from Kalman to Kaplan
Kane is the most common name in this section with over fifty thousand bearers in the 2010 census.
It has several origins, including being an Anglicization of the Jewish name Cohen.
Kaminski and Kaminsky are variants of a name with Polish and Ukrainian origins. The meaning comes from the words for “stone” in those languages.
It was conferred on people who came from the many towns with similar names. Those towns were likely named from the stony or rocky terrain around them.

Names from Kapoor to Karsten
Karr is the most common name in the U.S. census in this section.
It is a variant of Karrer, which does not have many bearers in the United States. Karrer is of Germanic origin.
The meaning refers to someone who made and repaired carts. In English, this trade was known as a cartwright.

Surnames from Kawa to Keebler
Kay is the most common name in this section with about twenty-four thousand bearers in the U.S. census of 2010.
There are differing theories about the origins in England, but it’s possible for several to be true at once!
Some point to the Old Norse word for a jackdaw which sounds like the call of the bird i.e. “ka”. Others point to the Middle English word for someone who is left-handed.
It may be derived from the word “key”. Such a name would be conferred on the families and descendants of a locksmith.

Names from Keech to Kegley
There are several popular Irish names in this section which I’ll discuss in a separate article.
Instead, I’ll look in depth here at Keeler. If you think it’s got something to do with boats, then you’re right.
“Kele” was the Middle English word for the keel of a boat. A “keeler” was someone who built boats. The name was conferred on the families and descendants of boat and ship builders.

Last names from Kehl to Kelliher
Kelley is by far the most popular name in this section. The variant without the second “e”, i.e. Kelly, is far higher. You’ll see that number in the next section.
We’ll cover Irish names in a separate article. Here, I’ll look at Keller, which is just under one hundred thousand bearers.
You would be mistaken if you thought that Keller was a variant of Keeler (we discussed that in the previous section).
Keller has Germanic origins and is derived from the German word for a cellar or storage room.
The name was conferred on servants in charge of pantries in large estates. It could also be given to tradesmen who kept their wares in cellars.
