I use mostly vintage machines, most of them are named for their former owners. My 2 Singer 66 red eye treadles, are named Ruth, after my Dad's mother, Sandy after my bff who gave me the 1910. The Pfaff 60 treadle is Gertrud(she needed a good German name). The 1914 Singer 115 treadle is Opal Violet, she has a big rust spot on her face; so she needed a pretty name. The 1936 Singer 201k treadle is Randie. The Featherweights:Tan 1961 is Freddy,1936 purple repaint is Gloria,black 1957 is Patty.
