There has been much discussion about the lack of sources on profiles so I thought that I could offer an example of an easy way to do this. I started with the profile in this example and searched only on familysearch.org and yes there are other places to search but this one is totally free and has citations that can be copied and pasted without much work. The sources show enough information for others to check them including a link and most even have a link to images that can be viewed for free. Some may argue that they are not the proper style or are too long but they work and the profile only had the statement of the information coming from a 2011 GEDCOM upload I feel that it is a major improvement with very little effort. My total time spent on this profile was less than 2 hours and I even took the time to eat breakfast in there.
If we all took the time to do just one profile like this every day the number of unsourced profiles would quickly be reduced to almost none in a very short time.
So join me with this endeavor, others can always make the biography better later and even change the source style as long as they have the basic information to start with.
