The Old Country

'The Old Country' is the English-Speaking country which Abraham Simpson claimed to have come from in Much Apu About Nothing. This country is said to be the land from which the Simpson family originated.

Which Country is it?
Abe is unable to remember exactly which country he is from. This is likely due to his poor memory and his dementia. However, it is likely in Europe and is likely a country in which the Simpson surname is well-established. It could be one of the following states:

Ireland
Ireland is a country in Europe. It is a candidate for the 'Old Country' as the Simpson name is common in Ireland (Although the name has it's origin in Scotland and England) and also the accent spoke by Abe's father could be described as similar to the Irish.

Scotland
Scotland is one of the four countries which make up the United Kingdom. The way Abe's father pronounces 'Tomorrow' (Ta-morra') is similar to the way 'Tomorrow' is pronounced in a Glasgow accent. The way that the word 'Live' is pronounced is also reminicent of the Scottish accent. The Simpsons being from near Glasgow would make sense as Glasgow is a major port city on the west coast, so America could easily be accessed by a boat.

Canada
Canada is another possibility as this is where Virgil and Mabel Simpson fled to in 1860. Here, they had a son, Abraham Simpson I (Abe's great Grandfather). Canada however, is unlikely as the accents spoke by Abe's family do not resemble the Canadian accent. It is quite possible that the story of the Simpsons fleeing to Canada is false and made up by Abe, due to his forgetfulness and dementia.

Sweden
In The Simpsons Uncensored Family Album, Homer's ancestors were hinted to be Swedish. However, the book is considered to be non-canon and the Simpsons may not have Swedish origins. Furthermore, the country in the show was shown to be an English-Speaking one. English is not spoken in Sweden.

England
The accents spoken by Abe's parents could also be described as being similar to those spoke in the North East of England. The pronunciation of 'Tomorrow' as 'Ta-Morra' is often heard in Tyneside and Sunderland accents. The way Orville pronounces 'Going' and 'Home' is similar to the way that people from Newcastle, Sunderland, Teesside and parts of Yorkshire pronounce these words. The style of buildings and the clothing of background characters are similar to rural Yorkshire.
