In the biography of a scholar of the last century I found mentioned that he was an offspring of al-Hafidh al-Mundhiri المنذري the author of the famous hadith collections (on recommendations and prohibitions) called at-Targeeb wa at-Tarheeb الترغيب والترهيب. And further more the author of that biography pretended that al-Mundhiri was of the offspring of the sahabi Khalid ibn al-Walid, but didn't add any reference. Imam Shams ad-Dyn a-Dhahabi شمس الدين الذهبي who was a student of al-Mundhiri's students didn't confirm this in his well known biography collection "siyar a'laam an-Nubala'" سير أعلام النبلاء (see here -in Arabic-).
I'd like to know if any Muslim historian or biograph or author of a book on 'ilm ar-Rijal confirmed this statement.
