These two families emigrated to Ohio in the early days of settlement, locating in Clark County and nearby counties. The Helvies came from Pennsylvania by way of Montgomery County, Virginia. The Mocks were from Pennsylvania, but I haven't been able to trace their route to Ohio.
The two families were joined by the marriage of Frederick Mock and Nancy Helvie on February 22, 1852 in Clark County. They had 12 children, including Margaret J. Mock, who married James Thomas Boone and gave birth to my grandmother, Belle Boone Green. For details for this family, see my Boone family page.
This family has been traced by other researchers back to Carlen Helwig. He emigrated to this country from the Palatine region in Germany, arriving in Philadelphia on August 24, 1749 in the ship Elliot, Captain James Adams, from Rotterdam via Cowes. He settled in Hempfield Township, Lancaster County, Pennsylvania. Here is the lineage from Nancy Helvie back to Carlen Helwig.
Carlen's Great-Grandson Samuel Helvie lived in Pike Twp., Clark county, Ohio when he died. He and his wife Margaret were listed as the owners of 70 acres of land in the northern part of Township 3, Range 10 in Pike Township, according to several maps from the 1860s and 1870s that are available on Ancestry.com. His land was near several pieces of land owned by Wiley Jenkins, who was executor of his 1862 will. Wiley Jenkins was the younger brother of Margaret Jenkins, Samuel Helvie's second wife. Here is a register report on the descendants of Samuel Helvie.
Frederick Mock was born in Pennsylvania on 28 Nov 1787, according to his burial memorial. He was married to Barsheba Priest, daughter of Jeremiah Priest and Emelia Gardner, in Miami County, Ohio on September 5, 1811. He bought a farm in about 1810. He was a mechanic, built the first wagon in the township, and made the buhrs in the first mills in the county.* Here is a register report on their descendants.

Note: I found a Frederick Mock, age 45 and up, in Franklin County, Pennsylvania in the 1800 Census, who had a son age 10-16. There were a number of other Mocks in that county in the 1790 to 1820 Censuses.
