Helen Sewell (and Mildred Boyle for some books) was the first illustrator of the "Little House" books. In 1953, the new editions were published with Garth Williams' illustrations.

Laura Ingalls Wilder named her daughter Rose Wilder Lane. Rose Wilder Lane was a well-known writer and journalist in her own right, known for her collaboration with her mother on the "Little House" series of books.
Laura merely says in the book "about two weeks".
Laura never specifically said what her single favorite food was (if one), but she does mention in her books a few favorites: Roast pork, and Oyster Stew to name just two. She also had a lifelong fondness for candy.
Laura had two cats. When she lived in Wisconsin, she had Black Susan. When she lived in the Dakota Territory, she had Kitty.
Laura's story Pioneer Girl is an adult autobiographical account of her life, with only subtle differences between it and her children's books. Laura's daughter, Rose Wilder Lane, wrote two books that are an adult version of some of the material covered in Laura's children's books-Let the Hurricane Roar (later called Young Pioneers) and Free Land.
Laura probably considered her greatest tragedy to be the death of her infant son at two weeks old.
Laura Ingalls Wilder had two children. A daughter Rose and a son, who passed away in infancy, unnamed.

Not much - the Civil War ended two year before Laura was born.
