Crimean "Goths" could as well be Saxons,read about their origin,there is no real agreement on their ethnicity.Crimea prior to the Tatars was Genoese trading center.
Let's see now opinion on scholars about possible connection of Chernyakhov culture where Goths were located with Wielbark.
This migration Scandinavia-Wielbark to Chernyakov is more a myth than reality.
So Tomenable please this things aren't proved,at least is good to mention that.
Ultimately as i said we need Chernyakhov culture DNA for Goths.

Guy Halsall sees no chronological development from the Wielbark to Chernyakhov culture, given that the latter stage of the Wielbark culture is synchronous with Chernyakhov, and the two regions have minimal territorial overlap. "Although it is often claimed that Cernjachov metalwork derives from Wielbark types, close examination reveals no more than a few types with general similarities to Wielbark types".[14] Michael Kulikowski also challenges the Wielbark connection, highlighting that the greatest reason for Wielbark-Chernyakhov connection derives from a "negative characteristic" (i.e., the absence of weapons in burials), which is less convincing proof than a positive one. He argues that the Chernyakhov culture could just as likely have been an indigenous development of local Pontic, Carpic or Dacian cultures, or a blended culture resulting from Przeworsk and steppe interactions. Furthermore, he altogether denies the existence of Goths prior to the 3rd century. Kulikowsky states that no Gothic people, nor even a noble kernel, migrated from Scandinavia or the Baltic. Rather, he suggests that the "Goths" formed in situ. Like the Alemanni or the Franks, the Goths were a "product of the Roman frontier"
