Morgan, once split evenly between the sexes, is a strong and attractive Welsh favorite, still a common boys’ name in Wales. Morgan is now more often a girls' name in the U.S. – about 2000 girls were given the name in one recent year, vs. 362 boys – though it's one of the most traditional unisex choices. Morgan was actually a Top 200 pick for boys in Victorian Britain!

Mack, when "formalized" with the final k, makes an engagingly amiable choice, a far more uncommon alternative to the ubiquitous Max and Jack, with a nice, every-guy feel. Mack entered the popularity list in 2009 for the first time since 1989 and continues to climb. However, it's still far from its peak — it was a Top 100 name in 1900.

Marshall is an occupational surname, not having to do with anything military or martial, but stemming from the Norman French for someone caring for horses.

Maverick meets Merritt in this strong sounding choice, which has its origins in Welsh, German, and Scottish. Notably borne by dancer Merrick Hanna, comedian and presenter Merrick Watts, and by Merrick Tremayne, the central character of Natasha Pulley's novel, The Bedlam Stacks, it was briefly bumped into the US Top 1000 in 2016 following The Supreme Court saga of Justice Merrick Garland.

Could it be time for a comeback?

In the USA, Maurice was in the Top 200 for most of the 20th century; since 1990, however, it has been on a slow and steady decline. This name has the potential for some old-school cute nicknames such as Mo as well as the more trendy Reece.

Mitchell has had something of a roller coaster ride, showing some panache in the forties and fifties, when it was seen as a sharper alternative to Michael with its cool Mitch nickname, slipping a bit, then resurfacing in the 90s when it reached as high as Number 71.
