With the misspellings of many names, one census is popping up that is most likely your Herman Bullion.
1900 Weakley TN
Ethelbert A 45
Mary E 4--
Knox L 22
Lena B 18
Birdie B 13
Mike D 9
Ella May 4
found the two census you posted.
also, I found one Eldridge Bullion of Kingsport TN
born 1897 who married Bertha Barnes.
then first name and the dates line up for Herman...
knowing that names were spelled as prounounced, finding many errors of spelling over the years of researching, as for now, I would say this 1900 census is your Herman.
