When George Frederick was 27 years old he emigrated to America on the ship "Patience" from Rotterdaym qualifying on August 11, 1750 (Pennsylvania Archives, Series 2, Vol. 17, page 308: also Pennsylvania German Pioneers, Stassburger-Hinke, Vol. 2, page 488 - Library of Congress F 146 P 23 Vol 43). The journey to America was a brutal affair for these early immigrants. They first boarded flat bottom canal boats that traveled down the Rhein River to Rotterdam, Netherlands a distance of around 300 miles. This required two to three months. Arriving in Rotterdam, they boarded sailing ships for Philadelphia. The first stop was the Isle of Wight on the English Channel for final supplies. Departure awaited favorable winds and weather conditions.

After five to six months they finally arrived in Philidelphia, their first act being a declaration of citizenship and allegence.

George Frederick settled in Pennsylvania apparently first near Philadephia where he was attending the St. Michael's Evangelical Luthern Church, Germantown when his eldest son, Johann George Groh was born in July 1751 and was christened (Records of the St. Michaels Evangelical Lutheran Church, Germantown, Pennsylvania on microfilm at Genealogy Society Library). The date of his marriage or his wife's maiden name in unknown. The ship lists only recorded the male names, it is suspected however that he brought his wife Maria Barbara from Wuerttemberg with him.

Shortly after arriving in America George Frederick bought a farm of about 163 acres in Lower Merion Township near Philadephia on the Schuylkill River.

Richard W. Grow photographed the Family Bible on a visit to Ardmore, Penn in May 1963. The bible was in the possession of George M. Grow of 1914 Lycoming Ave. Abington, Penn., a third great grandson of George Frederick Groh. On the inside of the front cover Frederick identified the day and place of his birth and on the inside of the back cover he kept records of the birth of each of his children. His bible was printed in Germany in 1746 and was probably brought to America when he came. Many notes were made in the bible either by him or his descendants, but these two pages are the most interest to the Grow family. Five children were noted in the bible apparently did not survive childhood. One son David lived 34 years but apparently did not marry. Five children survived both Frederick and Maria Barbara. These being the following: Johann George, George Adam, Maria Catherine, Jacob and Henry.

The old family home is still standing on Grow hill at Ardmore, Pennsylvania and has been lived in up to the present. Frederick helped to found St. Paul's Lutheran Church at Ardmore. He was one of the six trustees representing the Lutheran congregation who bought 63 acres in 1765 as a site for the church and burial ground (Norristown Times Herald, Friday, November 9, 1934). Many of the Grow family were buried in this cemetery, the Lutheran Cemetery of Ardmore, Pennsylvania.
