I've mentioned several of these district line changes on forums and in chats but wanted to blog about this. There seem to be a number of district boundary line changes in court in the later part of the 1850s in Bedford Co TN.
From the Minute books of the Bedford Co. TN Court.(1848-1860)
1855 Feb Term pg. 413(page 119 of Marsh book)
On petition of John Jackson, William G Hight, William C. Cook, Thomas Davis, Jno W Manier, William King and Jno Boyce, it was ordered by the court that the line of Civil District #11 be changed as follows, to wit, commencing at Weakley's Creek and running with the public road by Hight's to as to include the lands of the petitioners from District #9 to #10. 21 justices voting in the affirmative.
Also on page 413 there is a petition by Robert Allison which can be seen at FamilySearch(log on required but access is free with registration)
1858 July Term pg. 195(page 142 of Marsh book)
