They are mulberries, yes, but they are actually White Mulberry (Morus alba), an invasive tree in North America that has spread across much of the continent. Red Mulberry (Morus rubra) is our local native species (which can be found over the Eastern half of the U.S.), though it's fairly rare to encounter one given the abundance of White Mulberry in developed areas. Black Mulberry (Morus nigra) is another non-native mulberry species in the U.S., though not found in Maryland.
