I live in Belchertown so getting over to Quabbin Park is no problem.
As for moving picture order around just go to the memorial of Dr Segur, which you are the manager/owner and click the photos tab (upper left) and then choose the [Edit Sort Order] and using the arrow buttons you can select/move the desired picture to the "front" of the list which will display that picture first on the memorial page.
You may have already figured this out but if not I hope it helped.
And yes, Find A Grave can be a bit narrow on their views of what is appropriate but it is still a very cool place to share genealogy information. Cheers
Jeremiah Armstrong Got your message about Jeremiah. Is he a relative? I also ordered Howes book from the library. I will update as you wished.
I read over the Willard Segur memorial you created and I was very impressed.
One suggestion I would add would be to move the Drs picture to the front of the memorial in the list of pictures but otherwise that was one of the best documented memorials on Find A Grave I have seen. Brian
