You definitely do NOT want to merge the tree, or any part of it, into yours.
There is always a way to find the original record in the original database. Be sure to notice how the name is spelled in the record when you do a search. You can either do a search from the search page and then "drill down" through the areas on the left (ie census, birth, military, etc.) or drill down in a browser and, once the record is found, copy and paste the url to your WebSearch workspace.
