(The spelling differs a great deal among researchers
and changes over generations, and indeed, one theory is that during the Civil War, Unionists maintained the 'W' while sececessionists dropped it...but this doesn't always bear out*)

* See Andrew Jackson Turnbow, subject of Charles Turnbo's "Texas Turnbo's" who kept the 'W', but yet was a Confederate soldier in the 17th Texas Infantry along with his nephews Hugh, John Wesley, Willis, and Allen C. Casey.

***Please note that George Turnbow, b. 1766 was married a second time to a Margaret Clarke, and had several children by that second marriage (on my GEDCOM or Register Report, but not listed here for brevity's sake.)

John Andrew Turnbough was born ca. 1740 in Alsace also known as Alsace-Lorraine, which is an area of Western Europe which is now part of France, but over the centuries it has been alternately part of Germany then France, et cetera.  I am not familiar enough with the history of the 18th century in Europe to know if Alsace was more French or German in the time of John Andrew Turnbough's birth, but the name Turnbough sounds distinctly more French than German to me.

He immigrated to the New World in the 18th century, and probably participated in the Revolutionary War as a horseman.  Documents in my possession (copies) show that he was employed and compensated by one of the armies (unclear if it was the British or American army) for his duties, and was paid in "Pounds, Shillings, and Pence."  ***Anyone who has received SAR/DAR status through this Turnbough, who was PROBABLY a patriot from South Carolina, please notify me!

John Andrew Turnbough was my 6th great grandfather, and as is evident above, I descend from his great-granddaughter, Jane Turnbow Casey (see photo of her gravestone below).

Jane Turnbow Casey, b. Nov. 30, 1815 (caption on photo is in error) in Tennessee, and d. June 16, 1901, in Farmer, Young Co., Texas.

She married James Hill Casey (1813-1901) in 1832 in Wayne Co., TN, and moved to Williamson Co., TX in 1851. 
This photo, along with a similar photo of James Hill Casey, her husband, was formerly located in the rotunda of the courthouse of Williamson Co., TX in Georgetown, Texas in a group of photos entitled "Pioneers of Williamson Co., TX".  It is now in the Williamson County Historical Museum (WCHM) in Georgetown, Texas.
