Where were the dead children of Anne Bolyn buried?

The remains of Anne Boleyn's children, Elizabeth and Edward, were not buried with her. Instead, they were interred in the Chapel of St. Peter ad Vincula at the Tower of London, where Anne herself is buried. However, historical records regarding the exact burial locations of her stillborn son and any other children are sparse, and their graves may not be individually marked. Elizabeth I, Anne's daughter, is buried in Westminster Abbey.
