I never put my tree online,the problem is there are many people who just want to take any shortcut they can and grab parts of trees and add them to their own,many do not seem to care if the tree they have taken is correct,I also have tried in the past to tell people that they have made a mistake in their tree but it is useless people just do not want to know,this has happened more with computers and software ,it has become too easy for people ,they just do not want to find out things for themselves,in a few years it will be possible to put you name into a site and for a fee have your entire tree given to you,then this great hobby will be finished,I am just glad that I started years ago when you had to travel to local records to find the parish records,and have the thrill of seeing something written about your family in the margin or at the bottom of the page which will never be recorded because it is not on the page proper
