A tribute mentions her brother Michael.

Same date of birth as (Edward) Michael Pakenham

Though Michael's exact date of birth is not given in Burke's (only the year is given), the full date is on his findagrave page at:

In short, I believe that Joan P Breiter must be Michael's twin sister Joan Compton Pakenham, born 1932, whose married surname is known to be "Breiter". The "P" must be for "Pakenham".
