Arthur Lloyd was an actor, singer, comedian, song writer and music hall performer who lived from 1839 - 1904. He was very famous in his day, but like most Victorian entertainers he is largely forgotten. Since 2001, his great grandson, Matthew Lloyd, has been trying to rectify that by creating a massive website dedicated to him.
If you are doing anything involving Victorian theaters or Music Halls, go here first! This site has over 2,000 pages and 5,000 images on their history. There are photos, programs, songs and posters. Think of it, your character could go to a Music Hall on a particular night and you now know what it looked like, and who was playing there.
The site also has period maps and a timeline that tells what else was going on in a particular year.
