[citation needed] Tealby church, built using local orange-iron stone, is dedicated to All Saints and dates back to the 12th century; it holds memorials to the Tennyson d'Eyncourt family.

The King's Head, one of two public houses in the village, is one of the oldest in the country and retains a thatched roof.

[2][3][4] In 1807 a ploughman working for George Tennyson uncovered an earthenware pot containing a hoard of some 6000 silver coins.

[5] For a long time the placename Tealby has been attributed to Anglo-Saxon tæfl/tefl "gaming-board", here for a square piece of land, plus Old Norse -bȳ "dwelling".

But there are old spellings Tavelesbi, Tauelesbi and Teflesbi, and the Anglo-Saxon word tæfl is feminine and so its genitive would be tæfle, and therefore Caitlin Green suggests that the name refers to some Taifali (a horse-riding Germanic or Sarmatian people) who invaded Gaul or were brought into Gaul by Romans as mercenaries and later crossed to Britain with the Anglo-Saxons.
