John Anderson of Virginia and Kentucky

I am looking for the ancestry of John Anderson (1760-1826) who was born in Virginia. He was in Montgomery County, Kentucky by at least about 1800. There were four John Andersons in Montgomery County making them difficult to trace. He married Mary Robeson about 1798 probably in Montgomery County, Kentucky. The marriage records of Montgomery County, Kentucky burned in the Civil War. Robeson is also spelled Robinson and Robertson but it is Robeson in his son's family Bible. Nothing is known of the Robeson family either. John Anderson died intestate. His children are considered to be James Robeson Anderson (1799-1867), Margaret, Ann, John F. Anderson [the F. may stand for Fowler](1803-1870), Matthew William Anderson (1807-1827), George W. Anderson (1810-1859, my ancestor), and Robert Smith Perry Anderson (1814-1874). No parents or siblings of John Anderson are known. His grandson married a Daniel descended from a Daniel family in Middlesex County, Virginia. A biography his grandson says John was born in Virginia. The date of his coming to Kentucky is unknown. I seem to note members of the family were not in military service and owned no slaves although they had sufficient affluence to be slave owners and owned land in a slave state. My great grandfather, Matthew William Anderson (1836-1906), refused to serve in the Civil War for either side. After the War he was a Banker in Independence, Missouri. There were a large number of Andersons in early Montgomery County, Kentucky and surrounding Counties of no known relationship to one another. William Anderson LaBach in Lexington, Kentucky.
