My favorite first ladies are, from the 19th centuray, Dolley Madison:
From the 20th, a tossup between Edith Roosevelt and Barbara Bush:
FRom the 18th centuary, both Abigail Adams and Martha Washington:
I don't need to tell you the one from the 21st centuary!
Still, I am so glad I didn't live in the 18th or 19th Century. How would we get along without (in no particular order) a microwave, computer, TV, telephone, modern medicine, mascara, curling iron, jeans!
