Originally settled in 1826, Calvin Wheeler built several mills here in the 1840s and it was originally known as '''Wheeler's Mills'''. In 1848, a post office opened under the current name, named after
Tamworth, Staffordshire. Wheeler was an admirer of Sir
Robert Peel, member of Parliament for Tamworth. The area was settled by many
Irish immigrants and by 1865 the population of the area was 500. In 1884 the Tamworth and Quebec Railway had three trains departing to Napanee each day. Once the forest cover had been removed the soil that remained was not of the best quality, but farmers persevered and the area included many cheese factories. Farmers could supplement their incomes cutting trees in winter to be floated down the
Napanee River to mills in the south. Tamworth today is a mix of farms, homes and cottages on Beaver Lake and includes the services such as churches, hockey arena, car wash, restaurants, a hardware store, grocery store, pharmacy, liquor store, library and many others. ==Gaeltacht==
