I'm currently inquiring around the family for more information. It would be good if we could communicate directly but the website might not allow the passing of obvious addresses. Anyway, try jcingoa at hotmail dot com (or the equivalent!!). All I can tell you at the moment is that my Grandfather, Charles (Carl) Clemens, was the son of Casper (Clemens) Coenen and Gertrude Clemens. He married my Grandmother, Amy Billingsley, daughter of William Selby Billingsley and Emma Porter, and continued the family line - they had 13 children. If you are part of the Clemens clan, you have a lot of cousins you may not know about.
