My 1897 Singer fiddle base is Ida, after my grandmother, who was born in 1888.
The 1913 Singer red eye is Leota, after my other grandmother, who was born that year.
Mom's 1957 Singer 201 is Dottie, my mother's nickname.
My Singer 99 Centennial is Miss Lily, after my granddaughter, who is also "small but mighty."
The Singer 301 is Marion, after my 88-year-old aunt, who still uses her 301 regularly.
I have a 1940s 15-91 in the basement that I have even cleaned up yet, so no name given.
My "modern" machines, a 1980 Kenmore and 2007 Brother, do not have names. I just feel drawn to name the vintage ones.
