I bought the domain mapping service from WordPress some time ago which in turn posts all of my posts from the TimCohn.Wordpress.com blog address to TimothyCohn.com .
As recommended, I also added Google Webmaster Tools to the site to monitor and measure how well this site is performing in Google.
I recently received a notification the site map submitted by WordPress was not being correctly read.
I resubmitted the Sitemap to Google Webmaster Tools and shortly thereafter I received the following data in Webmaster Tools dashboard.

Sitemaps No Errors
As of October 4th, the sitemap.xml submission for TimothyCohn.com has been successful.
