My name is Robert Coe Jr., and I'm also a descendant of William and Mary Adams, and live in Wheatland. Williams daughter Blanche Adams Brown was my great grandmother. I can remember my grandmother telling me 50 years ago that we were related to the Romeslbacher family. I'd be curious of any information you have been able to find. I did locate Mary Adam's tombstone at the very remote Clear Creek Cemetary in Nevada County several years ago.
