That little town of Yterrby has gobs of elements named after it: erbium, yttrium, ytterbium, terbium. A bunch more were discovered in the same region. Fun story... in the publication of the breakthrough discovery of the high-temperature superconductor YBCO, the researches deliberately mis-reported the formula as containing ytterbium throughout the peer-review process. At the last minute before publication, they emended their paper to the true formula, containing yttrium. Their work won the 1987 Nobel prize in physics.
