This site gives post offices and postmasters. http://www.usps.com/postmasterfinder/ This site takes a while to search but I went to Postmasters and where they served", typed in Bunker (pays to have an uncommon name) and came up with Bunkers dating back to 1827 and as recently as 2001. You can type in a place and get information about it or ask for post offices in existence on a certain date. This is the Post Office website and it has lots of information. The site says it has information back to 1963 when in fact it has lots of information back to the early 1800's. I asked for a list of post offices from 1800 to 1825 and it said there were more than 500 listed. Some queries will get a response that research on that post office has not been completed but this site has a lot of information useful to genealogists. Since it has so much to search do not give up when it takes so long after you enter your query. It is worth the wait. This one is a little strange for a genealogical list but if you are interested in endangered species try this site http://www.arkive.org/ This is actually a very informative site if you are just interested in descriptions and pictures of animals and plants. Here you need to click on the words and not the box to get where you are going. Happy 4th. Bette
