Grafton Centre Cds Information On This Post Office Please

Hello, I have this cover with a Grafton Centre, Nh cds. The only thing I could find on this post office was it was in operation from 1852-1893. The only mention I can find for this town is a list of stage coach times, other than that nothing. Can someone direct me to where I can find information on this post office? Your help, as always, will be most gratefully appreciated.

I had to crop this down to this as the optimizer would not let me take the width lower than 370. The return address is:
Fidelity Lodge #75
I.O.G.T. (Int'l Order of Good Templars, West Canaan, Nh. and was posted to West Concord, NH.

Grafton Centre a post office of Grafton Co NH and a station on the Northern Railroad 2 miles NW Grafton and 46 miles NW of Concord

For what are you looking to know?

Gilbert W Rollins was the Post Master in 1866.

Horace Barney was paid 39.43 as Post master, year unknown.

Thanks to all for the quick replies. The information you provided was pretty much what I was looking for. I just wondered where the town and post office were located as the only information I could find was on Jim Forte website as to dates it was in operation. I am most gratefull for the information.

No problem. I just googled.

Hello again, I never thought to use the word postmaster in my search and that made all the difference. Your first reply got me to wondering if Grafton Centre was a town or just a post office for the railroad to pick up outgoing mail for the county. That led me to this site. Thanks to your replies, now I know. That is what I love about SCF. There is always someone who can answer your question and get you on the right track.Thanks again

I used, "Grafton Centre" "NH" "Post Office"

This is my first day here but I do research for a lot of history stuff, with my work (unpaid) for a local museum of which I am the President.

Grafton Centre, 1852-1893, and Grafton Center, 1893-1955, the same town.
The minor spelling change came about as part of the standardization of city names by the Post Office Department in the early 1890s.
