Martha Morse, the first of the Little House girls, grew up to be Laura’s great-grandmother. A spunky and rebellious redhead, Martha was the daughter of wealthy landowners in the Scottish Highlands. She learned needlework, as did all proper young ladies of her time, but she much preferred exploring the rolling hills around her home with Duncan, her brother and best friend.
