No.
The accent of native Marylanders really depends the part of the state in which you were born. Where I live it’s a little southern-sounding, but then there’s a heavy dose of Baltimore...it sounds strange.
A lot of people who live in Maryland weren’t born in Maryland too, so they bring their southern, northeastern, Midwestern et. accents with them.
They have a funny (if not downright ugly) accent all their own. Water is pronounced “wuter”; house is pronounced “hise”; when someone tells you that he or she is going to the Atlantic beaches, they’ll say that they are “goin’ donn de aoshin”; oysters are pronounced “urshters”; Baltimore is pronounced variously “balmer” and “bowl-tee-more”; and the state is pronounced “Murlin”. This accent spills over into parts of southeastern PA, Delaware and northern/Chesapeake Virginia. The preposition “on” is pronounced “own”.
