D.T. Lahey is a retired Ontario teacher and department head of English. Lahey’s interest in genealogy led to research of Sir George Simpson’s origins, his wives, and his children. He has published articles breaking new ground in Simpson research in Families: The Journal of the Ontario Genealogical Society, and lives in Guelph, Ontario.

"Lahey's passion for his subject is obvious, and his decision to draw upon Simpson's own writings and those of his contemporaries to give voice and historical credibility to the biography is admirable. He makes a compelling argument for the study of Simpson as one of the Makers of Canada."
