Dear Ernie, Thank you so much for your prompt and thorough response and I'm so glad to hear the house is still standing. What an interesting history it has, too! There have been so many historic and lovely houses lost to development in Essex County, including several others pictured in Samuel Chamberlin's book. I have cousins who live in Andover and the next time I visit them, I'll suggest we go find the Abbot house! Thank you again. Sincerely, Kathy Greenough
