During the summer and early fall of 1955 there were a series of hurricanes. I am not sure about their names, but one may have been Diane. During one of the storms several houses in the Pemberwick / Glenville area were washed into the Byram River. Subsequently, the Army Corps of Engineers assisted in re-configuring that section of the river to avoid similar future situations. The Greenwich Library may have some Greenwich Time archive photos of the incident.
