Sometimes a move or line is given a generic label (e.g. "5.a3 Variation"), but when possible it is given the name of the person known to have played it first.
(This is based upon my 9 years of research into the Jerome Gambit. Of course, further discoveries may change things.)
There are a few exceptions (e.g. 5...Kf8, the "Sorensen Variation"), where the name given refers to someone who did significant analysis of the line, or greatly popularized it (e.g. 7...d6, the "Blackburne Variation").
