Rivka Leah Leibowitz

From Voronova and Soletchnik Yizkor Book, p401:

"In our times the main Rabbi of Great Soletchnik was Khanokh Sharshevski. He was a scholar and well known in Rabbinical circles, not only because of his virtues but also because he was the son of the Gaon Chofetz Chaim's sister. He didn't have sons, and one of his daughters married David Leibovitsh who took over after his death.

R. David was a "parush" [someone who left his home to study Torah], who migrated from town to town looking for Torah houses until he ended up in Soletchnik, wed, and settled there."
