I have info. about Hefners in North Carolina, Jacob is in my line of research. However, There are many Jacob Hefners in that time line that includes his daughters birth in 1833. One of my GGGGradfathers was Jacob Hefner b. 1 Nov.1763 in Frederick Co. Maryland moved to North Carolina in the late 1700s. He had a brother Named Phillip Jacob that was b. 16 Jan.1768 in Frederick Co. Maryland, moved to North Carolina in the late 1700s. He died in Catawba County, North Carolina 11 Feb.1858. The first Jacob died in 1814 so it could not have been him, but he had a son named Jacob that could have had a daughter born in 1833. If I can find her Parents siblings or anything about her I will pass it on to you.
