内容简介：
Ancestors of the Moore/Walser families have lived in the Ann Arbor area continuously since the Civil War era. In addition, members of the Riggs family have been part of the University of Michigan in one way or another since our Grandfather, Henry Earle Riggs, founded the Department of Civil Engineering in 1910. Although most family members now live elsewhere, I thought it was appropriate to acknowledge this lovely college town, where two families once got together, and where my own grandchildren now form a seventh generation.
