Pearl and Periwinkle is a novel for children written by Anna Graetz. Excerpts from the book:

But even he would have felt sorry for Miss Hetty this morning. To adopt two children when you know nothing whatever about their care was by no means a pleasant prospect. Besides, these children were the son and daughter of the outcast of the family, an only sister half-forgotten though only two months deceased. The thing itself was pathetic, yet it seemed an imposition: above all to adopt two children who had traveled all their young lives with a circus was at least to Miss Hetty's mind almost scandalous.
