On June 26, 1799, a wing of the Hessian Barracks on South Market Street in Frederick, was destroyed by fire. On June 26, 1826, the Carroll Creek through downtown Frederick flooded, damaging the property of many citizens, including Jacob Engelbrecht's on West Patrick Street. On June 26, 1958, The Historical Society of Frederick County announced that it was now in possession of the Jacob Engelbrecht Diaries. Mr. Engelbrecht recorded local, national and international events in numerous journals from 1819 until his death in 1878. It is a unique record of local deaths, births, marriages, and just plain everyday tragedies. (The Society has published The Engelbrecht Diaries. The new volumes include more than 100 pages not included when the book was first published in the 1970s. It is available through the society in both book form and on a CD.) On June 26, 2011, the Sergeant Lawrence Everhart Chapter of The Sons of The American Revolution dedicated a plaque at the grave of Dr. Philip Thomas, the first physician in Frederick County. The ceremony took place in Mount Olivet Cemetery in Frederick. Dr. Thomas was the son-in-law of John Hanson and served as a colonel of the 4th Battalion and provided medical support, money, food and supplies to the Continental Army during the Revolutionary War. Dr. Thomas was born June 11, 1747, and died in 1815 in Frederick.
