11. The denominations thus far noticed are chiefly of German origin. The next class contains those of Scottish origin. Among these the Presbyterian holds the first place in age and numbers. The first organization here was made in 1706, and known as the Presbytery of Philadelphia. Their first synod was convened September 17, 1718.
The first General Assembly met in 1789, and a more efficient and extensive development ensued. In 1810, a division arose, and the formation of the "Cumberland Presbyterian" organization. But the most extensive division took place in 1838, by which a body was organized and known as the "New School," while those who remained were designated as "Old School" Presbyterians. The split thus made has continued for thirty years, but is now ostensibly removed by measures of reunion.
The statistics of the "Old School" Presbyterians for the year 1863 first show the effect of the separation of the Southern portion during the war. The report of numbers has been as follows:
