The bar of Northampton County shared this preeminence, and for more than a century it has maintained its prestige in the front rank of the profession in the commonwealth.  Its roll contains the names of many distinguished and able lawyers who have also been in high official station.  It is not my province in this paper to catalogue them but it will suffice to mention Samuel Sitgreaves, Judge Hopewell Hepburn, Judge Joel Jones, George Wolf, governor of Pennsylvania, James M. Porter, twice president judge and secretary of war in President Tyler's cabinet; Richard Brodhead, a member of Congress and senator of the United States; Peter Ihrie, Henry D. Maxwell, Sr., Henry Green, chief justice of Pennsylvania, Judge Kirkpatrick, attorney general of Pennsylvania; Howard J. Reeder, judge of the Superior Court of Pennsylvania and General Frank Reeder, secretary of the commonwealth of Pennsylvania...
