(Located on upper Market Street about a block north of the Samuel R. Dunlap home and standing on the edge of the river bluff overlooking the present "Cabin Cruiser Docks.")
The Samuel Davidson home was approached over a long driveway from Market Street The house itself was a large three-story red brick structure with a three-tiered porch facing the river.
The Davidson family operated a saw and grist mill on the river flat a short distance north of their home. Log rafts would be floated down the Allegheny and Ohio Rivers and then brought up the Beaver River to the Saw Mill. Here they would be "snaked" across old Water Street (now known as Riverside Drive) to the mill. Originally Water Street ran its entire length along the edge of the river bank. While the Davidsons would be hauling their logs from the river, traffic along the street would be blocked. To eliminate this condition, the Davidsons petitioned the State Legislature to abandon the street at that point and they would furnish an equivalent amount of land farther inland. This "swap" resulted in the bend in the street as it is today.
A daughter of Samuel Davidson was married to Walter Dunlap, a son of Samuel R. Dunlap, and this couple lived in the Davidson home for a number of years.
