Confederate Cover - Looking For Info On Postmark

This cover is one that I would like to learn more about. I am interested in the "Black MP CO, SC cancel". This is one I have not seen before and it seems worth additional research. I am interested in where it was generated. I have done some rudimentary on-line searches but so far have come up empty. The MP might lead to a Military Police (or Post maybe) not sure. The reverse is clean and provides no additional information.

If anyone has information or can lead me to a book or other research material that would be appreciated. It may be very simple (and common) and I am just not looking in the right places.



Thanks in advance for your time.

Black Mingo, SC

(My method on this was to go to Jim Forte's postalhistory.com website, the post offices list, then South Carolina, then search for the string containing "black". It was among approximately 15 results.)

Williamsburg County, open intermittently 1850-1895.

Hobsun, I am very much in agreement with John on this. Jim Forte's is a fantastic website especially if one is interested in the postal history of the state / county one lives in

John / Peter,

Thanks this was an over-sight on my part. I was aware of Jims' site and agree it is a great reference. I had a quick look early on but was so focused on what I perceived as "MP" that I passed right over "Mingo". This one seems correct and on closer inspection Mingo fits. I should have picked up on that one (red face). Now I can look to see if anything interesting shows up for Matthew Williams in Black Mingo or Chester CH from this time period.

As always, thanks again.

Added: Here is a tidbit I found on the Black Mingo PO that I found interesting. It was found in the Charleston Mercury dated 6/16/1850.
