My mom got me interested in genealogy she did a lot of research on my dad's maternal ancestors the Cessna's. After my mom passed on I started researching on my own and soon found out the depth and extent of documentation that Diane Sutor Greenwood had already done and had already published. She continues to research along with Charles W. Bill Cissna, Jeff Lightner, Cheryl Cessna, Krista Cessna and others. Thank you
