I maintain a website called "Blackmore Site" which is intended to provide a resource for anyone researching the BLACKMORE surname. Over time I have collected data which is available directly on the website, some examples are:

Extracts from UK, and Canadian census returns.
Extracts from Australia, Canada, England, Ireland and US directories.
Selected Court, Cemetery and Parish records
The US Social Security Death Index.
and several others ...

I've also provided links to guide you in your research.
