A number of women who authored children’s series came from writing families, with parents, siblings, cousins, or other relatives also publishing in some fashion. Another group had connections to the clergy, with fathers or husbands (or both) serving as ministers or teaching religious studies. One small subset of this population was sisters who wrote girls’ or children’s series and who had ministers as fathers. The earliest such pair were Elizabeth Stuart Phelps (1815-1852) and Sarah Stuart Robbins (1817-1910), daughters of Andover theologian Moses Stuart (1780-1852). The most successful – in terms of series fiction ‑- were probably the Mathews sisters, who specialized in religiously themed series and devoted most of their writing careers to works for children.
