📜 Duff Through the Generations
Through the generations, Duff has remained a quietly uncommon choice that's never broken into mainstream popularity. With just 441 total births recorded in US history, it peaked modestly in 1954 with 34 births, a year that likely reflected mid-century trends favoring short, sturdy masculine names. The average bearer is now 73 years old, and a striking 363 of the estimated 281 living Americans named Duff are over 60, while only 6 are under 30. That tells us this name didn't sustain momentum into later decades. Globally, it's ranked #162,945 with about 2,127 living bearers worldwide, and most of them reside in the United States. The trend line is stable rather than declining sharply, suggesting a small but consistent trickle of parents still choosing it. Duff sits in an interesting space between classic and modern, carrying a punchy one-syllable energy that doesn't feel dated even if its peak was nearly seventy years ago. It's a name that could easily see a quiet revival.
