His mother was Katherine Champernowne, the third wife of Walter Raleigh senior, and the fourth daughter of Sir Philip Champernowne (1479–1545), lord of the manor of Modbury, Devon, by his wife Catherine Carew, a daughter of Sir Edmund Carew (d.1513) of Mohuns Ottery (in the parish of Luppitt), Devon, and widow of Otes Gilbert (1513–1546/7) of Greenway (in the parish of Brixham) and of Compton Castle (in the parish of Marldon), both in Devon. (The coat of arms of Otes Gilbert and Katherine Champernowne survives in a stained glass window in Churston Ferrers Church, near Greenway.) Katherine Champernowne's paternal aunt was Kat Ashley, governess of Queen Elizabeth I, who introduced Raleigh and his brothers to the court. In addition, Raleigh's maternal uncle was Sir Arthur Champernowne (c. 1524–1578), a Member of Parliament, Sheriff of Devon and Admiral Of the West. Walter Raleigh junior's immediate family included his full brother Carew Raleigh, and half-brothers John Gilbert, Humphrey Gilbert and Adrian Gilbert. As a consequence of their kinship with the Champernowne family, all of the Raleigh and Gilbert brothers became prominent during the reigns of Elizabeth I and James I.
