Any yDNA candidates around down from James Junken?

Question

I'm very interested in hearing from any direct male line descendants of James Junken of Perthshire who might be willing to venture into fully sponsored yDNA testing to clarify where more precisely lines "fit" together.

Here's a blog post on the history of this request:  https://lornahen.blogspot.com/2023/04/those-magic-three-words-new-relative.html

Anyone can help the search by extending or updating the lines down from any of the family :)
