Frederick was the next to the last son of Jacob Grumbach. He was born in Frederick County Maryland. Sometime around the year of 1795, Frederick was wedded to Ester "Hetty" Gress in Cumberland County, Pennsylvania.

Her mother died sometime after 1800, although it is not known where or when her death occurred.
During the 1800 Federal Census Count, Frederick was listed as Head of Household in East Pennsboro Township, Cumberland County, PA.
According to "The History of Columbiana County, Ohio", published in 1879, "Frederick Crubaugh was one of the original settlers in the western part of Centre Town-ship in 1808, along with Gabriel Laird, Robert Blackledge, Jesse and Conrad Brandeberry, George Lee, Henry Harlan, Andrew Kuhn, and Martin Breidenstein." This group of pioneers settled sections 28, 29, 30, 31, 32, and 33 of Centre Township. Frederick settled in the southeast part of section 33.

Either, or both of these children may have been born in East Pennsboro Township or in Centre Township, Columbiana County, Ohio.
