James Jakes, but which James Jakes?

Is this my Paternal Great Grandfather James Jakes among the 37 persons drawn to serve as jurors for the April 1880  term of the United States Circuit Court. It is not his grandfather, James Jakes as he passed in 1847.  It could be his uncle James Jakes.  His Uncle James Jakes also married a daughter of James Morrow & Margaret Sutton. The children of this Uncle were my Great Grandfather, James Jakes' Double 1st Cousins.

My Gr Grandfather, James Jakes(b. 1857) was not yet married and was boarding with the Armstrong family in 1880 in Dist 1 of Bedford Co TN which contains Fairfield.

This Uncle James Jakes(b. 1825) had been living in Coffee Co TN in the previous census years.  However, in 1880, he too is in Dist 1 of Bedford Co TN with his family.

Nothing conclusive so far.  Could be either of them.  Records of the US Circuit Court Middle District of TN for the April 1880 Term would be where I'd need to check.  Surely he would have had to give identification.  The age would be the telling factor.  Better yet, if for some reason he could not serve.there would be more paperwork no doubt.  Now to see if I can locate where any of those records would be housed, if there is access to them and record of those called to serve.
