Paltree on Family Tree Circles

I'm just beginning to build my tree back from Richard Graham & Mary O'Donnell Graham. Came to America 1826, first settled in Pennsylvania. Their son, John Graham & wife Rebecca Logan ended up in Oregon. I don't have much before their arrival in the US. Do have a great account of their lives through the Civil War and arrival in Oregon via an account by Dr. Benjamin Graham Horning.
Anyone have any hints?
