Hi Donna- On Nancy Rood, I'm not sure on her age, but her tombstone says she died in 1872 at the age of 60, so that would make it around 1812 when she was born. Transcribed records of Pownal marriages say she was married in 1831, so she would have been around 19 possibly? On Thomas and Nancy's son William, this is what I have: William P. Larabee born January 27, 1841 and died September 22, 1905. He is buried in Oak Hill Cemetery, Pownal, New York with his wife, Jane Pratt. Jane was born December 9, 1837 and died November 14, 1885 at the age of 47.
Now...where did I find the information on the East Lawn Cemetery? I actually just stumbled on it by sheer luck on the Internet. If you go out to the Massachusetts GenWeb and select Berkshire County, then in Berkshire County click on "Berkshire County Towns", then select "Williamstown". It will bring up a scanned book of Birth, Marriage, and Death records. I found Eleazor and Ruth in the BIRTH records just by chance. There is a guide for the abbreviations on the pages and it says in the guide that anything with a G.R.3. listed at the end of the line, means they've gathered that information from grave stones in Eastlawn Cemetery. So that is how I kind of stumbled on that and learned that they are actually buried in Eastlawn. It was in kind of an unsuspecting place I guess. You wouldn't think it would be listed in Birth Records.
