A pedigree dataset representing the familial relationships among key figures in the Wars of the Roses, a series of English civil wars for control of the throne of England fought between the houses of Lancaster and York during the 15th century (1455–1487). The pedigree is rooted at Edward III (r. 1327–1377), whose numerous descendants through multiple lines of succession gave rise to the rival dynastic claims at the heart of the conflict.

Details

The dataset is useful for illustrating complex pedigree structures, including multiple mating events, consanguineous marriages, half-siblings, and the kind of dense, overlapping family networks that characterize historical royal genealogies. It includes Wikipedia URLs for each individual, making it suitable for teaching pedigree construction and relationship tracing with reference to publicly available biographical sources. Twin and zygosity fields are included where applicable.

Pedigree integrity was verified and phantom individuals were added as needed using checkSex, checkParentIDs, and checkPedigreeNetwork from the BGmisc package. Family group assignment used ped2fam.
