What was daily life like in Georgian England? (circa 1690-1830)?

Question

I'm mostly interested in the daily life of people living in Ireland or London in the mid- 17th Century, what they wore, ate, said even what the insides of their houses looked like.

Answer 1

That's a huge subject; I recommend you acquire Liza Picard's "Dr Johnson's London", which gives fascinating insights into people's lives in the 18th century. It describes manners, dress, homes, sewage - everything you need to know! Subjects also include the way people spoke and how they curtsied/bowed. She has written other books as well, covering other eras:

Meanwhile, here is a good site for costume:

I hope this is adequate for a start!

Answer 2

1. First you need to properly understand the terminology that you use.
a) "Georgian" - the Georgian era refers to the reigns of Georges I, II, III and IV, and thus the period from 1714 to 1830.
http://en.wikipedia.org/wiki/Georgian_period
b) "1690" - the starting date that you quote, was during the reign of William and Mary

c) "Mid-17th century" - this refers to an even earlier period, specifically around 1650. This was a time when England was a republic, known as the Commonwealth of England.

d) "England" - whilst London is part of England, Ireland has never been so.
