I am the gr gr gr gr gr gr gr grand daughter of Robert John Withrow born 1692 in Ulster Ireland. I seem to have run into a wall in trying to find information on Robert prior to his arrival in PA and his parents. The only listing I have is a Dorothy Strickland listed as his mother. I have also found a Samuel Withrow but I'm not sure it is the same Samuel that you have I think his Father William might be a uncle of mine. ANy Information you care to share would be greatly appreaciated.
