Others have struggled also.

The above is about the best summary around. It is loaded with amplifying links.

Answer 2

Another source to try is Halley's Bible Handbook. It's not online itself, but it's an excellent source. Still another might be Walking the Bible. Here's a link to the PBS series based on that book:
