Alright, I have researched the figures I originally came to, I couldn't find all the information I had acquired previously, some of it was hands-on at the library, and I'm at work right now, limited to the internet. But:

How, Elizabeth: executed at Salem, New England, on 19 July, 1692

that's a
lot more than 3. And those are only the Salem executions. The list is very comprehensive, up to date, up to the year 2003. And only includes
verifiable deaths of persons known by name, not those with no records, although there are further lists where the victim was not known by name, but the death itself is verifiable. 801 to date.
This site is the source of those names and dates.
