Mine have names but with the exception of my Featherweights they're rather tongue in cheek. My Featherweights are:
The white one is Elsa, the 1951 Centennial is Lily and the 1935 is Isabelle (Izzy). My Bernina was a "divorce gift" to myself so I named her Diva and my Juki is named Nellie because sometimes she gets going so fast my first thought anyway is "Whoa Nellie!" LOL
