There are two fantastic websites for the village Quorn, maintained by Tim Rodgers.
http://www.quornmuseum.com/ The Quorn museum website
http://www.quorndon.com/ The Quorn village website
The Quorn village website and also the Quorn museum website have so much information I cannot start to list it all here but it includes, census transcripts from 1841 to 1901 and also Quorn graves which were recorded in 1981 by the Women's Institute.
It is also great to see old photographs of the village.
Another recommend from me if your family came from Quorn and also if you live in Quorn and you are interested in the village history.
