History & Origin
Luby is a surname pressed into service as a first name. Its most common source is the Slavic root 'lyub,' 'love' or 'dear,' though some bearers connect it to Ruby instead. Used as a given name from the late nineteenth century, it stayed rare, cresting at only about fifteen boys a year around 1925 before fading. Its route in any one family is uncertain, which we note.
A Luby from its peak would belong to a great-grandfather's generation. Its warm two-beat sound sits beside Ruby, Toby, and Coby - the -by names - and it reads as antique. Because the source varies by family, we keep the meaning honest rather than fixed.
