The on-line version of The Forward has an article and podcast on the Twersky Family Tree.
The Twersky family tree has more than 25,000 names on it, and stretches back to the early 1700s, in the town of Chernobyl. The family not only boasts a legacy as a Hasidic dynasty - with the exception of a handful of Hasidic groups from Hungary, almost all Hasidic sects can trace their lineage to Twersky rabbis in Chernobyl
