Peregrine Bertie, 13th Baron Willoughby de Eresby

[1] Bertie was Lady Willoughby de Eresby's second husband, the first being Charles Brandon, Duke of Suffolk.

Peregrine Bertie's half-brothers, Henry and Charles Brandon, died as teenagers four years before his birth.

Owing to religious politics, his parents had to move outside England and the boy was born at Wesel on the River Rhine.

From March 1586 Bertie served in the Netherlands as governor of Bergen-op-Zoom under Robert Dudley, 1st Earl of Leicester,[3] who was Governor-General of the United Provinces.

Bertie's final appointment was Governor of Berwick upon Tweed on the Scottish border and Warden of the East March in 1598, displacing Robert Carey.

At the request of Robert Cecil he organised the kidnapping of Edmund Ashfield, an Englishman visiting James VI of Scotland.
