Mordechi Chaim Palewski - Merge?

Despite the slight mismatch in their respective fathers' full names, Mordechi Chaim Palewski seems to be identical to Mordechai Chaim Poliyer Palefsky - compare grandfathers: Moshe from Kovrin Palewski vs Rabbi Moses ben Israel Polier of Kobrin - and brothers: Noach Naftali Palewski vs Noach Naftali Rabinowitz. The Berman family source material makes it clear that the Palewski family intended is that of the Rebbes of Kobrin.
