Deletion of Heinrich Marx

Comment: I understand that notability is |not inherited but there is sufficient content here to warrant a standalone article. Also, when the main article gets too verbose, we usually  the content anyways. If we look at this article as an article about Karl's relationship with his father as a standalone article, which can't be merged to Karl Marx's article because it's too large, we can argue for a keep. Also, the section about his life cites a book (by Allan Megill) whose subject although is Karl, but it also focusses on Heinrich and his life too. In the "after conversion" section notable historian Isaiah Berlin writes about Heinrich in particular too, although again, the subject of the book is Karl. Also, the works section cannot be discounted/disregarded. Not having access to/or not having read the works doesn't mean they aren't notable works
