      :type family_pb: :class:`._generated.data_pb2.Family`
      :param family_pb: A protobuf
  
      :rtype: tuple
      :returns: A string and dictionary. The string is the name of the
                column family and the dictionary has column names (within the
                family) as keys and cell lists as values. Each cell is
                represented with a two-tuple with the value (in bytes) and the
                timestamp for the cell. For example:
  
                .. code:: python
  
                    {
                        b'col-name1': [
                            (b'cell-val', datetime.datetime(...)),
                            (b'cell-val-newer', datetime.datetime(...)),
                        ],
                        b'col-name2': [
                            (b'altcol-cell-val', datetime.datetime(...)),
                        ],
