Casper was born abt. 1735. His name appears on the List of Taxables for Brecknock twp, Berks County in 1759. In 1767 Casper is also on the List of Taxables as a farmer of 100 acres and owning one horse and one cow.

Casper might have been a soldier during the Revolutionary War. There is a Casper Koch in the records who served as a seargent.

Casper died prior to the marriage of his daughter Maria in 1784.

Johannes Koch was born abt. 1763 and married Regina Ruffner.

William Koch was born in 1798 and was likely married about 1822 to an unknown wife. William married about 1849 Susanna Siverling, b. 1827.

William and Susan were farmers in Caernarvon Township in Lancaster County. Their farm was siyuated just southeasterly of Turkey Hill. In 1850 the farm consisted of 53 unimproved acres and 12 acres of improved land valued at $4770. The farm machinery was valued at $100. The livestock William owned were counted as 3 horses, 6 milch cows, 7 other cattle and 12 swine valued at $341. Crops raised were tabulated as 100 bushels of wheat, 150 bu. of Indian corn, 300 bu. Oats, 15 bu. Irish potatoes, 300 pounds of butter and 15 tons of hay. The value of animals slaughtered was $87.
It is possible that Willam married Susanna Siverling shortly after the taking of this farm census information. Susanna's name does not show up in the 1850 census for this family. The Federal census lists William 52, farmer (property valued at $5500); Benjamin Koch 47,(brother of William and buried with William and Susan at Center Church), with property valued at $1000.

It is also possible that at this time William and Susan were married, perhaps a year earlier, and that William and Benjamin came ahead to this farm while Susan maintained the "old farm" in Brecknock Township of Berks County and later joined them.

In 1860, a year prior to William's death the farms still consisted of 53 improved acres, but the unimproved acreage had dropped to 5, all valued at ($7000). William must have sold 7 unimproved acres during the last decade or lost some to roadways.
