Summary
"Save Kelseyville" claim that the town name was arbitrarily assigned by the USPS in 1882 when they renamed the "Uncle Sam" post office.
But the name "Kelseyville" had been used since at least 1865. And the "Town of Kelseyville" was established in 1871 by a Lake County judge, and was used in the 1880 census.
Most historians agree that Kelsey Creek, and Kelseyville are named after Andy Kelsey.
However, "Save Kelseyville" speculates that Kelseyville is named after some later, benign Kelsey.
But the only alternative Kelsey candidates arrived in the area in 1861. As the town formed out of scattered ranches William Kelsay reportedly lobbied for his distant cousin Andy. Nor is "The Widow Kelsey" a plausible honoree.
Suggestions that Kelsey Creek was named after an early trapper "George Kelsey" appear unfounded: Fur trapper George Wyman, who lived near Sutter Fort, married Andy's sister America Kelsey. But there is no evidence that he, and little evidence that any other group of trappers, were in the Lake County area before Andy Kelsey.
"Kelseyville" is, and always has been, named after the evil Andy Kelsey.
Kelseyville Names
In his appeal for the Mexican land grant, Salvador Vallejo called the ranchero "Lup Yomi" ("Rock Village") and Kelsey Creek "Rio Lup Yomi", though it is not clear if that name was used contemporaneously.
American Pioneers and settlers called the area The Lake, Mister Kelsey's, Kelsey's House, Kelsey Creek and The Town of Kelsey. In legal documents it was usually Kelsey Creek Township or Kelsey. The post office was created as "Uncle Sam" in 1858. That was not used as the town name, although it did appear on maps.
Most historians agree that "Kelseyville" was named after Andrew Kelsey.
But "Save The Name" now claim that the town is not named after the evil Andy, but some later, presumably honorable, town founder. In a letter to the Record Bee, Save Kelseyville secretary Marilyn Holdenried says "The name Kelseyville is a name that was assigned to us in 1882 by the US Post Office.".
"Kelsey Creek" (the stream) appears in government records as early as 1863.
Extensive research shows that the name "Kelseyville" was first used in 1865, when there were only two families of Kelseys or Kelsays in the area: William Kelsay and "The Widow Kelsey". William Kelsay lobbied for naming the emerging town after his distant cousin.
Holdenried also says that "In 1882, this area of Kelseyville was not a legal district". But the "Town of Kelseyville" was established as an assesors district by a Lake County judge, on May 6, 1871.
The specific attribution of the town name to Andy Kelsey first appears in 1873. By that time the name "Kelseyville" was in almost universal local use.
In census records of 1860 the whole of the Lake (then in Napa county) was called "Clear Lake Township": In 1870 it was "Kelsey Creek Township" and by 1800 it was "Kelseyville".
Thus the change of the name of the Post Office from Uncle Sam to Kelseyville, was not the first stamp of official approval, but the belated recognition that local and official usage had changed.
A detailed rebuttal of the "Save Kelseyville" claims is in separate documents, https://citizensforhealing.org/stnk-knames.php and in Rerbuttal of Marilyn Holdenried letter to the Record Bee.
In Jan 2025 Lake County supervisor Helen Owens suggested that Kelsey Creek was named after an early trapper in Lake County, George Kelsey -- in the 1830's (even before Vallejo).
I found two candidates concerning "George", "Kelsey", "Trapper" and"Lake County":
- There was a George Kelsey, apparently the deceased husband of the "Widow Kelsey" Permelia, but he died in Missouri, in 1859 - before the Kelseys came to California.
- Another candidate is George Francis Wyman, who married America Kelsey, Andy Kelsey's sister: "When George first met America, he was a fur trapper. It was the next day after her father had died of smallpox [near Sutter's Fort]. He and his friend, Joseph Buzzell, had camped near the cabin where the Kelseys lived. They had ventured into California's interior, after hearing of the vast trapping opportunities, from Jedediah Smith." None of them are reported as having come to Lake County.
Trappers in Lake County
Of Young, Mauldin says (Lake County in the Beginning - probably also in the Mauldin files)
Of course, the Natives Americans in the area called Kelsey Creek "Hitch bidame", and Vallejo called it Rio de LupYomi.
