merge Sophia Stewart family tree

Hello - In my tree, can someone please merge the duplicates for Sophia Stewart's Rev. Henry Stewart (Rev. Dr. Henry Stewart) and husband Rt. Hon. Edward Litton, MP (Rt. Hon. Edward Litton)? Source: http://www.thepeerage.com/p38292.htm#i382911

Will I gain access to these new parts of the tree? It's currently listed as private.

Best,
Andrea
