The present article uses Suso de Toro's Sete palabras as a starting point for analyzing the protagonism of illegitimate children in the Galician novel since the Rexurdimento. Considered in a historical context and as a literary trope, the illegitimate child can be read as an expression of anxiety around a national identity rested upon a notion of purity, be it linguistic, ethnic or territorial. These unclear origins, rather than preclude the possibility of identity formation and history-individual or collective-can serve as a source for alternative histories and identities.
