Debie Oeser Cox has a great blog, Nashville History (http://nashvillehistory.blogspot.com/). She worked at the Metropolitan Government Archives in Nashville, Tennessee, but is now retired. It is a great resource for learning about the history of Nashville. In July she posted an excerpt from History of Nashville Tennessee by H. W. Crew (1890): Turnpikes and bridges in Davidson County, Tennessee. She also shares her memories of life in Nashville.
She also sometimes posts records that are useful to genealogists. I found my 3rd-great-grandmother Mary (maiden name unknown) on a transcribed list of Nashville building permits, 1892. She was listed as Mrs. Cox (her second husband was John Cox). I was able to identify her because her address was given. On 19 May 1892, she was granted a building permit for a fence. Another post that was helpful to me is Original Lots, Nashville, 1784. A map of the plan of Nashville, showing the lots, is included, and there is a link to a table (also created by Debie Oeser Cox), which provides information about each lot, including the grantor and grantee. My 6th-great-grandfather Andrew Lucas was the grantee for Lot 34; he received it on 30 July 1784.
