The Irish Twins — Lucy Fitch Perkins

Lucy Fitch Perkins (1865-1937) was an American children's book author and illustrator, famous for writing the "Twins" series of books. She wrote books giving pictures of child life in other countries, and then, for the benefit of American and foreign born children alike, she also wrote books which gave some idea of what had been done for this country by those who had founded and developed it.
