    • Meaning:

      "resolute protection"

It now sounds rather dated in Germany, however, having dropped out of the Top 20 there in the late 1920s and continuing to decline since.

More than doubling in use over the last decade, it was given to 115 boys in 2024.
  17. Osmond
    • Origin:

      English
    • Meaning:

      "divine protection"
    • Description:

    • Meaning:

      German
    • Meaning:
