I am the great great great great grandaughter of Ezra Cornell, the founder of Cornell University. My great grandfather is Pierre Cornell-d'Echert and his brother is William Cornell-Dechert. I don't know when or where or by who, but somewhere along the line "d'Echert" was added to Cornell, but ultimately my roots lie with the Cornells. If any one could supply any info I would really appreciate it. Thanks.
