As far as I know, Ticer may be a derivative of Tessier which is French. Another possible spelling is Tysor. Augustine Ticer's (whom I am descended from) grandfather Lewis, came here from either France or Portugal with two other brothers during colonial times and settled in Virginia territory. The elder Lewis Tysor had three sons; Lewis, Alfred and another I don't know the name of. Lewis migrated to Chatham NC and Alfred to the West. The nameless one stayed in Virginia. My research indicates that Lewis Tysor (Ticer) Jr. is the father of Augustine in Chatham, NC.
