I happened to be at the lirbary today for my own research and remembered your post RE: Meyer surname. The library has a card catalogue that contains references to variuos names found in the Memphis Room collection. It is not "complete" and certainly not inclusive of all books,etc. at the library; but it can be helpful sometime.

I found 22 cards witht he surname Meter. Following are some notes I quickly took from some of those:
Adolph Meyer Naturalizatiuon Record, May 17, 1900, Switzerland.
Alphonse Meyer mentioned in "Saddlebags to Science" by Patrcia M. LaPoint (this is a book about early doctors in Memphis area)
Alphonse Herman Mayer Jr. in Who's Who In Tennessee 1961
Ambrosin Florend Meyer died 1863, obit in "The Appeal"
Dr. August Werner Meyer in Prominent Tennessaens 1855.
Charles F. Meyer signatures of depositers in Freedman's Saving & Trust Co. 1865-1874.
Clem H. Meyer 1895-1966 Architects of TN until 1930.
David M. Meyer in UT Memphis medical school 75th Anniv.
Douglas Alexander Meyer in 1961 Who's Who of TN.
Flora S. Meyer article in "Press Scimitar" (newspapaer 3-18-71 and 3-19-71. (does not say what century)
