Thomas Dekker’s maternal grandfather was a celebrity in his own right. He was Alun Williams (born David Alun Williams, 1920-1992), a well-known radio announcer for the British Broadcast Corporation.

This is a brief bio of his mother mentioning it:

He’s sort of cute, reminds me of Jared Leto.

I’m happy to see that my guess is correct. :) I’ve seen him in two films (I thought he was a separate actor in both), but I thought he was of part Welsh ancestry. He’s got some Welsh features such as his ‘button’ nose.

he must have something Jewish

Dekker = is a german surname, but a lot of Jews have this name

and he has those eyes , reminds me of a young danny elf man (who also is Jewish)

I’m from the Netherlands and Dekker is not a German surname, but a common Dutch surname in the Netherlands. His surname refers to his dutch ancestry

agree. Dekker is quite Dutch. There were some Dutch professional cyclist with that surname, I have heard South Africans named Dekker too
