I descend from Dr. John H. Bush (ca 1770-1832 Caldwell Co., KY) and his first wife, Mary Rowland, d/o Rev. Reuben Rowland (1745-18096 Livingston Co., KY). Dr. John H. (Housen) Bush first appears ca 1790 in Newberry County, SC. He appears to be closely connected to but not necessarily related to a George Bush there with a son, William Bush. This William Bush md. Mary Thetford ca 1770. All 3 went to Caldwell/Livingston, Christian Co., KY ca 1800.
These same 3 came from out of nowhere. No one can find any previous records for them.
However, all three fall into the same DNA group with Charles Bush's William Bush AND the whole Abraham Bush line from Lancaster Co., VA
You can see why I am particularly interested in William Bush's origins.
