Harford County was formed in 1773 from the eastern part of Baltimore County. It contains Tudor Hall, birthplace of Abraham Lincoln's assassin, John Wilkes Booth. Harford County also hosted the signers of the Bush Declaration, a precursor document to the American Revolution.


The county was named for Henry Harford (ca. 1759-1834), the illegitimate son of Frederick Calvert, 6th Baron Baltimore. Henry Harford was born to Calvert's mistress, Hester Whelan, whose residence still stands as part of a private residence on Jarretsville Pike, in Phoenix, Maryland. Harford served as the last Proprietary Governor of Maryland but, because of his illegitimacy, did not inherit his father's title.


Havre de Grace, an incorporated city in Harford County, was once under consideration to be the capital of the United States rather than Washington, D.C.. It was favored for its strategic location at the top of theChesapeake Bay; this location would facilitate trade while being secure in time of war. Today, the waterways around Havre de Grace have become adversely affected by silt runoff, which is one of the primary environmental issues of Harford County.


The county has a number of properties on the National Register of Historic Places

What good is it all if you can't be there to enjoy it too! I have a great, supportive, and loving wife Kim, a daughter Jazmine, a son Christian, and my youngest daughter Cameron.

Helping people is what I do.  So the transition from Retail to Realtor® was pretty easy.  Some of the skills that I posses that will benefit you are:
