Murf, in my opinion, an old home does not have to have had some famous person from the past, or be centered around some actual event in order to be historical. When we read History or watch programs about it on the History channel, we hear about the more promenant people, like Abraham Lincoln, Gingas Kahn, and the like. We hear about famous or infamous events likt the 9/11 attacks, Pearl Harbor, the sinking of the Titanic or the Lunar landing.
To me, it's just as important to know and see how regular working class ordinary paople lived back then. Like us, people back in the 1800s argued politics. They married, h ad children, and lived life. The significance of an old house like mine, is that ordinary people lived there back in 1910. They argued about whether Wilson or Cooledge was a good president, much the same way my brothers and I argue about Barack Obama today. I caught the breaking news about the 9/11 attacks the very day it happened, in the very same living where in 1912, the residents read the news paper reports about the sinkjing of the titanic. The same living room where residents who lived there before me heard about Pearl Harbor on the Radio, or watch the assassination of JFK on a counsel black & white tv.
It's living, pure and simple. We hear a lot about Julias Ceasar, but I want to know more about how the 'working stiff' lived in ancient Rome. I hear a lot about George Washington, but I would like to know or see how regular "Joes" like me and you lived their lives in 1776. To study the works of Aristotle, Homer or Plato is fine, but what about the ordinary people of their day? What was life like? How did they live? What did they do for entertainment? How did they react to the "Pearal Harbors" or "9/11s" of their time?
A great way to know those things, or at least get a few clues is to study the houses they lived in.
At least that's the way I look at it. It's great that we still have Mt. Vernon and the old U.S. capital, but what about the homes where ordinary families resided?
