Wm

Were boys really named Wm at the turn of the last century, or was the old-timey abbreviation of William simply what was noted on the official records? We're guessing the latter, but as the Social Security Administration counts each spelling of a name in its tally and doesn't presume to change Wm into William (or Bryleigh into Briley, or is it Brylee?), this name stands as is through the ages.

Wm is also given to girls.

Pronounced WIL-yum.

As of October 2026, Wm ranked #8404 for boys in US births in 1992 and #4034 for girls in US births in 1930 SSA, peaked at #376 for boys in 1888 and #3336 for girls in 1920.
