This paper introduces four new intergenerational and multigenerational datasets which follow both sons and daughters and which can be used to study the persistence of longevity, socioeconomic status, family structure, and geographic mobility across generations. The data follow the children of Black and White Union Army (US Civil War, 1861-5) veterans from birth to death, linking them to the available censuses. The White samples include an over-sample of children of ex-POWs. A separate collection links grandchildren of White Union Army veterans to their death records. The data were created with high quality manual linkage procedures utilizing a wide variety of records to establish links.
