I am descended from Nancy Agnes Lusk (1753-1841) who appears to be a sister of your Thomas LUSK. She was married to William STEEN, who died in TN ca 1804. She and several of her children moved on to MS, where they were early settlers of Steen's Creek, Rankin County, MS. I have 3 generations beyond Robert LUSK (not my own research) if you are interested. I would be interested in any other information you have on siblings and ancestors of Nancy Agnes and Thomas. I would also like to know more about Mary VANCE's family.
