Before Maryland became the 7th State in 1788, it was a Crown Colony, chartered in 1632. The King at the time was Charles the First, and the territory was named for his queen, Henrietta Maria. A nice gesture, for sure.
Maryland has a lot of coastline around the Chesapeake Bay, as you see. Much fishing and sailing, and shipping. Plus a lot of varied weather and terrain. Plus likable Residents.
A Rhino Note: Black Eyed Susans, the Maryland state flower, are not poisonous, but they do offer nasty aftershocks if you overindulge.
