Maryland's flag bears the arms of the Calvert and Mynne families (the latter wrongly identified as the Crossland family in the act creating a State flag). Calvert was the family name of the Lords Baltimore who founded Maryland, and their colors of gold and black appear in the first and fourth quarters of the flag. Mynne was the family of Anne Calvert, the wife of George Calvert, first Lord Baltimore. The red and white Mynne colors, with a cross bottony, appear in the second and third quarters. This flag was first flown October 11, 1880, in Baltimore at a parade marking the 150th anniversary of the founding of Baltimore. It also was flown October 25, 1888, at Gettysburg Battlefield for ceremonies dedicating monuments to Maryland regiments of the Army of the Potomac. Officially, it was adopted as the State flag in 1904 (Chapter 48, Acts of 1904).
Maryland law requires that if any ornament is affixed to the top of a flagstaff carrying the Maryland flag, the ornament must be a gold cross bottony (Chapter 862, Acts of 1945; Code State Government Article, secs. 13-201 through 13-204).
