Tarshish

One of Javan's sons and Great Grandson to Noah. also the name of a place could the place be named after him?

Gen 10:4  And the sons of Javan; Elishah, and Tarshish, Kittim, and Dodanim. 

1Ch 1:7  And the sons of Javan; Elishah, and Tarshish, Kittim, and Dodanim. 

Est 1:14  And the next unto him was Carshena, Shethar, Admatha, Tarshish, Meres, Marsena, and Memucan, the seven princes of Persia and Media, which saw the king's face, and which sat the first in the kingdom;) 

There are several scriptures more that list Tarsish but they all refer to the place but once again is this named after Tarshish Javan's son?
