I had contacted Mt. Pleasant Cemetery in S. Portland, before my visit. The caretaker was able to direct me to many of the graves of my ancestors. Here are the ones I was able to capture.
John Armstrong (24 Feb 1787 - 27 May 1838) - Revolutionary War Veteran (my 3rd great-grandfather)
Betsey Woodbury Armstrong (16 Nov 1787 - 21 Apr 1876) - John's wife
John B. Armstrong (My 2nd great-grandfather), Jennie Campbell Armstrong and Clarence W. Armstrong
Robert E. Armstrong (My great-grandfather), Elizabeth M. Fuller Armstrong
Hugh Woodbury (My 5th great-grandfather) and his wife Jane Green Woodbury
I recently joined BillionGraves. They have a goal of capturing gravestones for over a Billion graves all over the world. This month they have a contest for those people who capture 1,000 or more gravestones using their iPhone app by August 31st get a BillionGraves T-shirt. I am up for the challenge and think I can do it.
Check out their website for more details. I am a big believer in having all tombstones available online.
