This first time line is by TeAch.nology.com whose web page was at www.teach.nology.com. As of March 2015, that link does not function. THIS may be the same site, http://www.teach-nology.com/
This simple but clean time line is by Read Write Think at http://www.readwritethink.org/
This extremely detailed time line is by http://www.ourtimelines.com/, it is so large that I had to do 6 screen captures to get it all, they are posted one after the other, sorry bout the breaks. The information in this time line is very interesting, showing how much Edna's world changed from the time she was born till she died. Only 3 dates from Edna's life appear here, her birth, marriage and death. (I note I have duplicated at least one entry during the process of my screen captures.)
These time lines were developed in 2010 for the blog post 91st Carnival of Genealogy, A Tribute to Women! The Time Line.
I may at some time just add these images to the post.
