Best known for writing a lively study of Mary Russell Mitford, this early-20th-century writer also produced descriptive books on London and the cathedrals of England and Wales.

by William James Roberts
William James Roberts was an author active in the early 1900s. The clearest web evidence available here links him to Mary Russell Mitford: The Tragedy of a Blue Stocking (first published in 1913), along with other books including Picturesque London and The Cathedrals of England and Wales.
The available catalog and reader pages suggest a writer interested in literary biography, place writing, and cultural history. Because the sources found in this search provide only limited biographical detail, it is safest to describe him through his published work rather than make stronger claims about his life.
A birth year of 1873 appears in your query, but I could not confirm that date from the sources retrieved in this conversation, so I have left it unverified here.
