Blanche Lyon Pursuivant

Blanche Lyon Pursuivant of Arms in Ordinary (sometimes Blanch Lyon) was a British office of arms created during the reign of King Edward IV.
In 1602, the office was made "extraordinary" for the appointment of Francis Thynne, before his promotion to Lancaster Herald of Arms in Ordinary that same year. Nicholas Charles held the post. John Philipot was created Blanche Lyon Pursuivant of Arms Extraordinary in 1613, and William Dugdale followed in 1638.
In 1784, Sir Isaac Heard had his step-son, Alexander Ochterlony, appointed Blanche Lyon. Ochterlony was the first of only two known American-born officers of arms in British history. The other was York Herald of Arms John von Sonnentag de Havilland
