The name of Rosenberger is of ancient origin in Germany, signifying Rosemount, or Rose Castle. The first settlers of the name of Rosenberger in Montgomery county came to the town ships of francoi'tia and Hatfield. The earliest of these was Henry Rosenberger, who came to the Indian Creek Valley in Fr'anconia in 1729. He was followed in 1739 by the coming Of Benjamin Rosenberger to Hatfield. In that year he bought 125 acres, bodering the county line at Line Lexington, which he held for five years. John Rosenberger came also to Hatfield and first bought land where is now the village around Hatfield station about 1749-50. Daniel Rosenberger purchased another tract in Hatfield lying along the county line near the hamlet called Bookertown in 1740. It is supposed that these families were all related and it is certain that Daniel and John were brothers. The descendants Of Benjamin are now largely settled in Bucks county. All the earlier members of these families belonged to the religious sect called Mennonites.
