The online Ancestry com census index does list Tomlinson as a separate locality. Below are the localities they do list:
Mountain / Boles PO
Tumbleston / Black Jack PO
Black Fork / Waldron PO
Blansett / Waldron PO
Lafayette / Waldron PO
Brawley / Waldron PO
Lafave / Nebraska PO
Washburn / Chismville
Sugar Creek /Reveille PO
Boone / Booneville PO
Hickman / Waldron PO
Hunt / Olio PO
Park / Waldron PO
Reveille

Although the census taker actually wrote "Tumnleston" on each census page, is it possible this was actually Tomlinson?

I am searching for the Thomas L (T L) POWERS family who lived in Tomlinson in 1860 but I can't figure out how he was mistyped on the AC census index. SO, I want to page through every census sheet for 1870 Tomlinson but I need to know how else it could have been listed ???

According to their children's births 1880 Yell County, they had to have been in AR in 1870.

My sincere thanks for any information you may share,
