It's up at the north end of town. Taking the exit from Rt. 7 to North Zane Hwy (5th St.), follow Zane Hwy south till it meets 5th St. Take 5th St. to Cemetery Road. Turn left at Cemetery Rd by Rose Cafe. DeHass is the first street on the left past the alley. It curves a bit. The big red brick house (I think) was Dr. DeHass's house. There used to be a trolley line at the end of the street before Rt. 7 highway was built over it and truncated the street.

A biography of Dr. DeHass is available from Annie Tanks' book on Martins Ferry.
