We're 200 posts into this problem and no closer to an answer, so I think it's time to trim away all the fat and get down to basics.
First, the chart of all the breaker assignments looks great, but if it was done by the previous owner, it may be outdated - not completely wrong, but things may have been changed.
Did you get any kind of meter or other tool to do circuit detection? It can be as simple as a "dummy light" (two probes and a LED light bulb) which will show you what's hot and what's not.
Have you opened junction boxes and checked to see if any wire nuts are loose? Don't trust just a visual check, sometimes a wire will appear to be inside the nut but it may not be twisted into the connection.
Start testing anyplace, but keep it logical so you won't have to repeat tests. If all the connections are good in a particular box, go downstream and check the next connection. If you find a dead connection, go upstream and try to find the last good connection in the circuit.
If a bad connection tracks back all the way to the breakers, you may want to call an electrician.
