mixed origins

Short definition from Wiktionary

Adjective

1. 1
   Having mixed racial, ethnic, or national parentage or ancestry. This term was promoted as an alternative to “mixed race” in a 1994 resolution of the Royal Anthropological Institute of Great Britain and Ireland, in part because of its correlation to mid-twentieth-century British laws using the phrase “race or ethnic or national origins”, but did not see wide use outside of the UK anthropology field
