Abraham (GOTTESZMAN) GOTTESMAN, Ha Cohen - Info??

This Profile has
"Curator Note from Adam Brown (9/7/2013):
Further research needed to prove that he is Mendel Gottesman's brother"

This is almost a full 10 years later. Has any research been done?

There is nothing in his Overview's About, nothing in the Abouts on his Timeline Events.

There are 4 entries in Media.
two are pictures, supposedly of him. Aside from the name of the Album they are in on Geni, and his name, and who uploaded it, no info about them.

The other two are Documents - one is
Partial Gottesman Family Tree.pdf. - appears to be perhaps the Descendant Report from Geni on 08 Nov 1910

The other is a large box with
"Publication Info: MyHeritage
אילן היוחסין העולמי של Geni נמצא ב-<A href="http://www.geni.com&quot; target="_blank">www.Geni.com&lt;/a&gt;. האתר Geni הוא בבעלות MyHeritage ומתופעל על ידה."
in the upper left, the rest totally empty - with 74 comments after that convey nothing to me.
If anyone can explain what it says, what it is, and what info it provides, I would be most grateful!
