Our story of Kathrynn
Our story of Kathrynn is about how a name looks on the page. Katherine has been written in English with a C or a K, with an e, an a or nothing in the middle, and the -ryn ending is the American contribution. Kathrynn adds one more stroke: a second n that closes the name the way Lynn and Glenn close theirs, so the written name ends on a firm double letter. Spoken, it is Kathryn, and no one will hear the difference.
