August 20, 1956 - March 8, 2021

Denis A. Hannan, age 64, of Sterling, VA died in hospice care on March 8, 2021 after a
lengthy, courageous battle with gastric cancer.

A native Washingtonian, Denis graduated from
St. John’s College HS in Washington
D.C in 1974
and attended the University of Louisville in Kentucky.

He spent his entire working career in Virginia, initially for the Virginia Department of
Transportation and subsequently for Fairfax County Government, where he retired after 28
years of service in 2014 as a Plans Examiner in the Environmental and Site Review
Division, Department of Public Works and Environmental Services.

He enjoyed U.S. history, public speaking (Toastmasters International), telling stories and the
outdoors and found the ideal outlet for of all these interests as a French & Indian War
re-enactor and historical lecturer. He traveled to virtually all the significant sites and forts of
that war, gleaning first-hand the details of that conflict that would populate his lectures and
presentations. Denis had both the exhaustive knowledge of the conflict and the booming
voice to address the groups that would gather to watch re-enactments of skirmishes and
events from the colonial period of the mid to late 1700’s. He delighted in the re-telling of the
story of colonial history to family, friends, veterans groups and other interested gatherings.
Denis was an ardent volunteer, supporter, and reconstruction contributor to Fort Loudoun, a
recreation of the 1756 historic fort, also a Pennsylvania State Historic Site in Fort Loudon,
PA that is. He spent many days assisting other like-minded volunteers with the ongoing
rebuilding of Fort Loudoun. Possessions were not terribly important to him in his life, but he
took pride in sewing his own period appropriate wardrobe for his reenacting avocation. His
most prized object was his custom-made and fitted, left handed black powder rifle that he
proudly discussed, displayed and fired during re-enactments and shoots. He found joy in
those endeavors, spending time with the other volunteers, informing visitors of the fort’s
history and significance and laboring at the reconstruction of the fort.

Denis will be missed by his extended family and friends. A lifelong bachelor, he was
predeceased by his parents, Denis T. Hannan and Margaret B. Hannan.

He is the youngest of five brothers and is survived by John P. Hannan (Jeannye) of
Dickerson MD, Stephen D. Hannan (Lynn) of Columbia, MD, Timothy W. Hannan of
Rockville, MD and Philip M. Hannan (Debbi) of Silver Spring and several nieces and
