Reginald W. (Reginald Welbury) Jeffery

Reginald Welbury Jeffery was a British historian, listed by The National Archives as Reginald Welbury Jeffery (1877–1956). He is chiefly known today for The History of the Thirteen Colonies of North America, 1497–1763, first published in 1908.

That book traces the development of Britain's North American colonies from the era of exploration through the mid-18th century. Modern readers most often encounter Jeffery through reprints and public-domain editions, which have helped keep his work available long after its original publication.

Reliable biographical detail about his wider life seems limited in the sources I could confirm, so it is safest to remember him primarily as a historian of early American colonial history whose surviving reputation rests on this substantial work.
