The above image is a snippet from the inventory of the Estate of Robert Boyd. Robert's will was written in 1837(Oct 26th) in Warren Co Tennessee. Van Buren Co TN was formed from part of Warren Co TN along with parts of White County & Bledsoe County. The act to form Van Buren county passed on January 3rd 1840 but according to the information in the act at the TN.gov site, it appears records didn't start until April 1840.
It looks at though Robert Boyd's probate records were caught in the middle of the formation of Van Buren Co. TN. A note from Will Armstrong, Warren County Clerk states that it(the will in the Van Buren Co Record Book) is a true copy of the original will on file in his office. So although the probate records start in Warren Co TN...they end in Van Buren Co TN but do have a copy of all the will there. In the will Robert left pretty much everything to his wife Jane to use in the support of his "little daughter" Ann. He appointed William Logue and John Boyd as executors. The listing of inventory along with the sale starts May of 1840 and wraps up July the 8th of 1840. I should note that although Wm Logue is listed on the will as executor along with John Boyd I don't see any more listings of him as a witness or purchaser at the estate sale. This adds more weight to this being William Marrs Logue, Robert Boyd's Father-In-Law who is known to have passed before September 4th 1839(I need to do a blog post on his estate info.). Wm Marrs Logue was the maternal 1/2 brother of my 4th Great Grandfather, John Fleming.
