In 1436, during the Hundred Years' War, people from the Low Countries were required to leave England or to take an oath of fealty to the Crown after the Anglo-Burgundian alliance collapsed and Henry VI resumed hostilities against France.
Many of these foreigners had settled in Suffolk. Details of 114 such men who took the oath are arranged alphabetically by surname in the attached table. They were published by the
East Anglian Daily Times in 1920 under the questionable heading "SUFFOLK ALIENS NATURALISED IN 1436" and reprinted on various pages (from 74 to 85) of
East Anglian Miscellany (numbers 5828, 5831, 5835, 5841, 5850 and 5856). The contributor (R. Freeman Bullen, an east London librarian) provided an example of the original format of the data recorded in the
Patent Rolls for one of the immigrants:
"Mandate to all bailiffs and others to permit Matthew Baker, of Holton, co. Suffolk, born in Skluse, in Flanders, dwelling in England, who has taken an oath of fealty, to inhabit the realm peac[e]ably and enjoy his goods."
The source is evidently the
Calendar of the Patent Rolls preserved in the Public Record Office, Henry VI, vol. ii, 1429-1436 (HMSO, 1907), where the corresponding entry on page 538 (made available online by the
HathiTrust Digital Library) reads simply: "Matthew Baker, born in Skluse in Flanders, dwelling at Holton, co. Suffolk". Mr Bullen appears to have taken the expanded text from an entry for a Middlesex resident on the previous page. He mentioned in his introductory article (
East Anglian Miscellany 1920 p. 72 no 5,821) that "practically all these persons were born in either Holland, Flanders, or Germany. Some of the place-names have been badly twisted by the Plantagenet scribe, but a little ingenuity will readily make out the name intended."
A hundred years later, we can consult a more comprehensive database, the authoritative
England's Immigrants 1330 – 1550, which helpfully gives modern names of locations both local and overseas. The
Background tab leads to a great deal of explanatory information, e.g.
Letters of Denization and Other Sources, emphasizing that the oath of fealty did not amount to full denization, let alone naturalization, and there are some particularly interesting observations on the
alien subsidy returns for Suffolk (1440-1483) and
other counties.
