Dog Names That Start With M

  1. Marshall
    • Origin:

      English
    • Meaning:

      "one who looks after horses"
    • Description:

      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. It's been used as a first name since the nineteenth century and has been on the Social Security list since it started to publish its data in 1880.
  2. Minnie
    • Origin:

      Diminutive of Wilhelmina
    • Meaning:

      "resolute protection"
    • Description:

      Minnie was wildly popular at the turn of the last century — it was the fifth or sixth most popular name throughout the 1880s — but is completely obscure today. Blame Mickey's girlfriend. Regardless, it's possible that the up and coming trend toward old-fashioned nickname-names — think Maisie, Mamie, Millie — may give Minnie (all on its own, not as a short form of anything) a new moment in the sun. Minnie Driver (born Amelia) has given it some modern celeb cred.
  3. Mireille

    • Meaning:

      "second"
    • Description:

      This spelling, which came to the attention of readers of the best-selling Angela's Ashes as the name of author Frank McCourt's father and brother, the latter of whom wrote a bestseller of his own, lends the biblical name a more expansive, almost boisterous image. Malachy is one of the Irish baby names that manages to strike the golden mean between familiarity and distinctiveness.

      English, combination of Mary and Lynn
    • Meaning:

      "drop of the sea, bitter, or beloved + lake"
    • Description:

      For a name that was in the Top 20 for a whole decade – the 1930's – Marilyn has attained the status of almost a one-person name. Just say the name Marilyn, and most people will know who you mean. Yet strangely enough, though Marilyn Monroe (born Norma Jean and renamed in tribute to earlier star Marilyn Miller) was the sex symbol of her generation, very little stardust adhered to her name. In fact, when Mariah Carey wished to honor the star in her daughter's name, she chose to call her Monroe rather than Marilyn.

    • Origin:

      Scottish
    • Meaning:

      "son of Kenneth"
    • Description:

      Originally inspired as by eighties TV actress Mackenzie Phillips, parents since have flocked to Mackenzie for their daughters. Now a staple All-American choice, Mackenzie has ranked in the US Top 1000 for nearly 50 years.

      Mackenzie originates from the Scottish surname which itself an anglicized form of the Gaelic Mac Coinnich. Coinnich is one of the original Gaelic forms of Kenneth meaning "handsome, beautiful, comely".

    • Meaning:

      "driftwood"
    • Description:

Just as Juniper is adjacent to June or Pippa, Clover like Chloe or Clara and Ember like Emma or Ebba, Maple is enough like Mabel, Maisie and Mae that it blends in well and has a touch of borrowed vintage charm.
