Remembering
John W. Cairnes
1949-2025
More than a Broker, John W. Cairnes was a pillar of the Harford County community who built a fifty-year reputation on the simple principle of treating every client like family.
John was a man defined by his roots, carrying forward a literal connection to the Maryland soil as the ninth generation of his family to live and work on their ancestral farm. This 250-year history of stewardship was honored by Governor Robert Ehrlich and the Maryland Senate, recognizing the Cairnes family as a Century Farm Family for their unwavering commitment to our state's agricultural heritage.
John’s bright smile, deep-rooted knowledge of Maryland land, and legendary integrity remain the heartbeat of John W. Cairnes Realty Co. today.
