I realise that the Book of Genealogies was lost a long time ago, perhaps after the Babylonian exile. See this question
Another explores the question as to why the tribe of Judah "was not lost" after the Babylonian exile.
In light of this, my question asking what happened to the genealogical records after Rome sacked Jerusalem and destroyed the temple in 70 A.D. might be superfluous.
Notwithstanding, I have been asked to provide a source for a statement I made that the genealogical records of the tribe of Judah and the house of David were utterly destroyed in 70 A.D.
If that statement is incorrect I need to know so I can rectify it and a link to a reliable source to explain what happened to the genealogical records would be most helpful. Thank you.
