Looking for Levi Bailor/Balar

Levi Bailor/Balar/Balor paid taxes on 2 cows and 2 horses in Belmont County, Ohio according to tax records prior to 1850. He may have a Will in Belmont County. He is a "Free Person of Color" according to 1830 and 1840 Belmont County, Ohio censuses. Levi is written as "Line Bailor" in the Ancestry.com indexes.
In the 1830 Belmont County census there are two males under 2 years of age, one male between the ages of 34 and 54, 2 females under 10 and one female between 34 and 54 for a total of 6 people. I believe this is Levi. I also believe W.M Balar, is Levi's son who is my 3rd great grandfather He may be one of the two males in the 1830 census household W.M birth year was recorded in the U.S, Censuses as 1827. W.M. Balar moved to Knox County, Ohio some time prior to 1875 as I found him in the non-population schedules for said county in 1870. He is buried at the Moundview Cemetery in Knox County next to his mother Diane.
I am trying to find more information about Levi's death, where he is from and the origins of the surname Balar/Balor/Bailer. I believe it may be misspelled and the correct spelling is Bailar as DNA matches have appeared with this spelling.
