This enumerator's handwriting is atrocious.  You really have to work to read it as "Brown," so I don't fault the indexer for calling it "Bunn."

10.  Hetty Sherwin.  nd.  The Early History of Fluvanna, Chautauqua County, N.Y., with Numerous Biographical and Family Sketches.  55 pp. Printed (i.e., not typescript), but has no date or publishing information.  It's two books in one:  the history of Fluvanna takes up the first 55 pages, then the rest of the book is about Griffith genealogy. (online at Ancestry.com; boldface added):

Early Settlement p. 15	...Antique Inn, owned by Mrs. Ida Thompson, was moved to its present site from the Shaw farm in 1866 by Alexander Brown...
Industries p. 23	A tannery was erected about 1828 by Alexander Brown, Jr., on what was known for years as the Shaw Farm.  Russell D. Shaw and Alexander Brown were schoolmates together in Berlin previous to their location in Fluvanna.  It was a pleasure to both Mr. Brown and Mr. Shaw that they were to be neighbors and continue their friendship with their business interests so near one another.  Mr. Brown continued operating the tannery until about 1846...
p. 32	This society [to build a multi-denominational church] was incorporated as the "Religious Union Society of Fluvanna," dated Feb. 1, 1842.  Signed by Alexander Brown, Jr. and W.H. Atherly on the 21st of February, 1842...
p. 45	ALEXANDER BROWN, JR. HOARD FAMILIES Alexander Brown, Jr. and Lucy Hoard, his wife, and two children, came to Fluvanna between Dec. 25, 1825 and October 1827.  He built a shingled house opposite Minor Shaw near the lake shore in 1828.  Mr. Brown also built a tannery near the western part of where the "Johnson Ice House" stood.  It was operated by him for a number of years.  [skipped a section on the use of tan bark]...
p. 46	...      Mr. Brown conducted this tannery until about 1846.  Mr. Brown died May 13, 1849.  Mr. and Mrs. Brown were the parents of ten children.  Lorenzo and Harry came with their parents; Samuel, Almon, Abagail, Alexander, George, Jane and Sarah, were born in Fluvanna.  Lorenzo, unmarried for many years, lived in the house now the home of James L. Brown (a nephew).  Samuel Brown married Abagail Gates; Abagail married Isaac Sherman; both of these famlies lived in Fluvanna until their death.  Sarah Brown lived with Mrs. Sherman until her death in 1917.  Almon Brown lives at Chautauqua; George and Jane went west to Kansas...  [moved the section on son, Alexander Sherman BROWN, to his page, q.v.]      Samuel Hoard, a brother of Lucy Hoard Brown, built a log house just east of the Bentley homestead.  He sold it to William Acocks in 1831.  He moved to Clear Creek, Pa.
p. 46	Samuel Hoard, father of Mrs. Lucy Brown, was also an early resident of the Townline road.  He lived in a log house on property now owned by Charles Phillips.  The house stood near where the old "creamery" was built in 1880 or 1881.  Mr. Hoard was buried in the Fluvanna Cemetery.
