Astor
The
Astor family were among the wealthiest in America in the 19th century,and toward the end of that century a branch moved to England and achieved great prominence there. As the 20th century wore on the family fortunes declined markedly, but their legacy lives on in their many public works including the
New York Public Library,and members of the British branch hold two hereditary peerages, a viscountcy and a barony.
