Victoria The MD. Purdums are all traced back to John Purdum from Wales. A biography of my Great Uncle Bradley K. Purdum appears in the Tercentenary History of Maryland. In this it states that prior to Wales the Purdums came to England from France with Williamthe Conqueror. Originally the family surname was Prudhomme and was changed to Purdum once they settled in Wales. As to a Reunion I know of none planned or being planned. If someone would like to put one together I would be interest in helping.
