According to the Voronova Yizkor Book (see 'About' section), Hanoch Sharshevski is the son of the sister of the Chofets Chaim. The way the tree is set up now (30 Dec 2019), Hanoch is made the spouse of the daughter of one of the Chofets Chaim's brothers, and not given a mother. At the moment there is one sister of the Chofets Chaim on the tree, Ryzel Kagan. I do not know whether this is the same sister who is the mother of Hanoch Sharshevski or there is another sister who is not yet named on the tree.
The suggested correction would be: 1) disconnect "? Sharshevski" (Badana Sharshevski) as the spouse of Hanock Sharshevski and leave his spouse blank, 2) make "? Sharshevski": a) the spouse of Yitzoch Eliezer Lipman Sharshevski (R' Yitzchok Eliezer Lipman Sharshevski) and b) the mother of Hanock Sharshevski, 3) Change the name of "? Sharsheveki" to "Unknown Kagan", 4) make "Unknown Kagan" the daughter of Aryeh Zeev Kagan (Aryeh Zeev Kagan) and Dobrosha Kagan (Dobrosha Kagan).
This would conform the GENI tree with the facts presented in the Yizkor Book of the town where Hanoch Sharshevski was the rabbi until replaced by his son-in-law David Leibowitz.
