Walsh did a lot of homework, collected some useful information, but in the end struck me as way too misty-eyed about "the legend." I have the book. LTF, if I may so address you: Google my name with Anne Rutledge. It will take you two articles I published in Journal of the A. L. Association. The second article, Summer 2010, provides a wide-angle critique of the Rutledge revival. I have to warn you: it's long (takes up half the issue). Maybe the first six pages or so are fun to read and then it gets very wonky. I'd guess that John Evangelist Walsh and a number of other authors who've published on A. Rutledge do not find it amusing.
And how on earth did you read about "heart of a thousand strings"? Henry Whitney quoted Lincoln saying that about "sexual contact." A striking thing to say for all kinds of reasons. Actually, it's quite an important quote. Where did you see it?
