Last names tell stories that first names never could.
They carry the jobs your ancestors worked, the places they came from, the land they farmed, the rivers they crossed, and the people they descended from. And the letter M carries more of those stories than almost any other letter in the alphabet.
Miller, Martinez, Moore, Murphy, Mitchell. You know these names. You have met people who have them. But do you know what they actually mean and where they came from?
Here are 129 common last names that start with M, organized by origin, with the stories behind them.
