Although she was seen as a being preoccupied by the high society for her whole life, Mrs. Astor was busy raising her children and keeping house for the first few decades of her life. The family moved into a four-bay townhouse built by her husband in 1862 at 350 Fifth Avenue, the present location of the Empire State building, right beside her husband's brother even though the brothers never got along.

After the Civil War, New York seen a very large population growth and the immigrants and people moving from the Midwest challenged Mrs. Astor's "grand dame" of New York's high society. This sparked "Lina" to set and maintain the rule of social behaviour and etiquette. This outline was once used by the city to determine who from the Midwest were acceptable. It was said that among the rich families of New York there were only 400 people who could be counted as members of Fashionable Society. This was set by the limitations of Lina's New York City ballroom.
Mrs. Astor died on October 30, 1908 at the age of 78. During the last years of her life she suffered from periodic dementia. She was buried in the Trinity Church Cemetery in upper
Manhattan. Her 39 foot tall cenotaph dominates the churchyard where many of the prominent early Americans are buried.

I think Mrs. Astor was an important person just not as important as everyone makes her out to be. I don't think that if I married a rich man in real estate I would be put in charge of the high society. She did shape what is expected of the rich and set the standard for "keeping up with the Joneses". But this can also be taken in a negative way and led to the conspicuous consumption and the unnecessary lifestyles of today's rich. It all depends on the way you look at things.
