Is Henry II Austin really one of he sons of the black prince (Edward of Woodstock)

Question

I was doing research on my father’s side and traced the Austin line back to a Henry II Austin who is supposedly one of the sons of the black prince (Edward of Woodstock). I found this on https://www.genealogieonline.nl/en/the-forgotten-ones/P60995.php

And 

https://www.myheritage.com/site-family-tree-283750461/neame?indID=1501387

I was wondering if this is confirmed anywhere. Henry II Austin did not show up on Edward of Woodstock’s Wikipedia page. If anyone could confirm this or provide any information on it, I would really appreciate it :)
