Statistical associations between late reproduction and female longevity led to speculations that a late birth increases a mother’s life span. The database used here includes all descendants of King George I of England (1660-1727) and his wife, Sophie Dorothea (1666-1726), born in the royal dynasties in Europe up to 1939 (n=1,672). In the era of British world supremacy, these descendants formed the uppermost layer of the European aristocracy, occupying all royal thrones from 1850 onward. Novel in this study is the use of pedigree information. In pairs of ever-married full sisters (brothers), both surviving to 45 (50) years, both having at least one child, the study examines whether the sibling with the first - or last - child born later in life also lived a longer life. This design controls for genetics, socioeconomic status, parity, social support, child mortality, birth cohort, and various environmental factors. In the 157 pairs of sisters and 191 pairs of brothers, later reproduction did not extend the life span.
