You say "I have review the other member tree and found everything is correct. Thier tree goes back to the 1780's where mine is so far only into the 1880's."

If you have evidence linking each person and place and relationship, why not just enter it in your tree together with citations to the evidence? Trees are not evidence; they may rarely be conclusions of someone who did actual evidentiary research, but nearly always they are the result of clicking to add stuff from other trees, or some copied gedcom uploaded. Many trees' saying the same thing is only evidence of copying, not evidence of accuracy.
