Uncertain, but probably a generic name like Jane, in reference to the device replacing a servant at table. Earliest attestation the 1903 Boston Journal, which credits local carpenter John Laurie as "the resuscitator of 'Lazy Susan'". Almost certainly not named in 'honor' of Thomas Jefferson or Edison's daughters named Susan.
