This is a post about the death announcement of Landon K. Cozad in San Diego, CA on Nov 3, 2012 a Cossart/Cozad/Cozart family researcher.
http://www.newtondailynews.com/2012/11/09/landon-k-cozad/a8g...In 2009 Mr. Cozad posted on a Cozad Message Board that he and his sister had published a single volume reprint of Six Volume Cossart Family History which was published in 1939 and was researched for about fifty years by the Cossart Family Association.
He was interesting and helpful, I am just sorry I didn't know about his passing till over a year later.
