I am trying to find the parents of John Foulk who I find in West Salem, Mercer County, Pennsylvania in 1850. I am descended through his son, William R. who was born October 10, 1835 in Ohio. In the 1850 census of West Salem, Mercer County, Pennsylvania, John and Jane "Fulk" are listed with William, Jonathan, ?, Levina, Lucy, Warren, and Arminta. The previous family in the census list is Samuel and Lena "Fulk" with children, George, Adaline, ?, as well as Elizabeth (age 66) and Margaret Gravat/Gravatt (age 66). Since the families are neighbors, I am wondering how they are related to each other. The age of John is listed as 44 and the age of Samuel is listed as 25 and they are both listed as having Ohio as their birthplace.
