Question:  Ælfwine Haroldsson, most probably an illegitimate son of King Harold Harefoot of England, and most likely left in his otherwise unknown mother's or grandmother's care, was the first wife of what king?
Sentence (from "Ælfwine Haroldsson"): He appears in an early twelfth-century cartulary from the monastery of Sainte Foi at Conques in Aquitaine as "Alboynus" (a cognate of Ælfwine), alongside the records that he was born in London and was the son of a King "Heroldus" (a Latinised version of Harold) and one "Alveva" ("Ælfgifu" Latinised).
Relevant evidence: No
