Have you rec'd information re your Dowden, Vandeventer and Howe families from your inquiry at Ancestry.com? I no longer live at New VA, IA, but still know a lot of people there and have some Warren Co., IA reference books. If you haven't rec'd any info yet, reply to this note and I will try to help you. (Am short on time at the moment and don't want to search unnecessarily, but will be glad to help if you need it!)
