An additional suggestion - if you are using any of the shared public 'one world tree's like WikiTree, Geni, FamilySearch, and to some degree Ancestry.com and FindaGrave, make sure the information there is correct also. I've been using so many tools and sites lately, with so many differences between them, but in the end they are ALL linked together, and bad and good info is slowly propagated around the world. While there are many users that simply copy what looks good, there are also many that do carefully check sources, and correct their own trees and the public trees, and thereby propagate the good info. Good and careful genealogists check the facts and explanations, so make sure to add them. It will often take awhile, but I've made corrections, and watched them slowly begin to propagate outward to others trees, and the public trees. In a way, we are all fellow collaborators on one big tree, whatever tools and sites we use.
Don't worry about the few that stubbornly stick with their version of the facts. Good facts with sources and explanations will go around them, pass them by, and spread to others. One great advantage of the publicly shared trees is that they are community edited, and generally, sooner or later, the truth wins out.
