Keeping the Prophets Straight

I have a difficult time keeping the prophets and their respective kings straight.  Perhaps I'm more concerned about this than I need to be, but I do like to know where people "fit" into the big picture.  I notice that many of us do this in our daily lives -- we meet someone new and try to figure them out by learning where they went to school, where they live, who they know, etc.  I suppose my concern and curiosity with regards to the prophets and their overall "place" is somewhat similar.  In any event, I've done a bit of investigating and appended an earlier chart of the kings of Judah and Israel with an extra column containing the associated prophet(s).  The ones with names in italics are those who don't have a separate book in the Old Testament.  And note that among the web-based resources I got this information from there is a lot of discrepancies.  In particular, Obadiah for some researchers is much earlier in the timeline, around the time of King Ahab.  A greater number of resources placed him towards the end of this timeline and so I've placed him there.  Here's the updated chart:

1010-970		David	Samuel, Nathan

If you'd like to do some of your own investigating, here's a list of a few web-based sources:

Again, I cannot and will not vouch for the entire content of these sites, but they (and many others!) do provide information that can be interesting/helpful/challenging as we read and study our Bibles.
