As per the project overview I have removed 4 siblings of Chaiim from the top of the tree.
Here is a summary of why the cuts were made
1) Eidel Elka Lebel Eintracht
Eidel was born in 1761 and died in 1827, her full descendant listing is part of the Jewish Families of Krakow Poland Project and is detailed at http://www.ics.uci.edu/~dan/genealogy/Krakow/Families/Eintracht.html
She was incorrectly attached to Shlomo Schlioma Voikhansky father of Chaiim Ber Voikhansky. This Shlomo was born in 1813 - when Eidel was 52 years old. So unless he was a time traveller he cannot be her father. There is the possibility that this date is incorrect and he was born before 1745 which would make him 83 when Chaiim was born - not impossible but there is no evidence to support this.
2) 3) and 4)
Rejzla Lipczak, Johann Jacob Kagan and Mordechai Knigin were siblings entered by myself in part of my own families dna journey. There is no evidence that this family intersects with the Voikhansky family. They do not appear in the ancestry.com tree. There may or may have been some bad merges made down the line in this tree. It is hard to tell as on the face of it the merges look okay right until you get to the very top merge of unknown to Shlomo.
Because Geni was updated with these incorrect linkages - there are now my.heritage trees that have been copied from them so there will get smart matches trying to reconnect them back to Shlomo unfortunately.
If there is any evidence that these should be added back in, I would be very interested to see it and will happily reinstate any connections.
