| | Rebecca Sophia Clarke and Sarah Jones Clarke |
 | | Rebecca Clarke (Sophie May) and her sister, Sarah Jones Clarke (Penn Shirley), were born in Norridgewock, Maine: Rebecca on February 22, 1833, and Sarah, seven years later, on September 12, 1840. |
 | | After finishing school, Rebecca Clarke moved to Evansville, Indiana, where she taught for a while until hearing problems forced her to return home.[1] She never married, but lived in the family home with Sarah Clarke, who was also unmarried and also producing magazine articles and children's books. |
 | | Sarah Clarke's ten children's books (three three-volume series and one individual volume) were published from 1886 to 1902, under the pseudonym "Penn Shirley." They enjoyed what could best be termed limited success. |
