The Dater Iron Works
This article, by John Y. Dater was first published in “The Old Station Timetable” in April 1979.
Abraham was the first Dater in this area. His dates are 1755-1830. He married Hannah Suffern about 1787. She was a sister of John Suffern and her dates are 1766-1823. Mr. Dater was much involved with John Suffern’s activities in the period before and after the Revolution. Mr. Suffern built his tavern before 1775 at the head of Washington Rd. and furnished camping space for Gen. Washington. It was not until after Mr. Suffern’s death that the town was called Suffern. He preferred the name Antrim after the county in the north of Ireland where he was born. Both men were very active in the early days of forming the Ramapo Reformed Church in Mahwah where they are both buried with their wives.
Another fact that helps date Mr. Dater was his membership in the turnpike company which was responsible for the road through the Clove from the Black Bridge over the Ramapo. He was associated with Aaron Burr in this venture.
Somewhere along the line Mr. Dater learned the iron business. He located in Sloatsburg largely because two Sloats and two Daters were married into the Hollenbake family of Dutchess County. On Stony Brook just north of Sloatsburg, Mr. Dater built an open hearth furnace, several forges and a saw mill, all of which used water power. On what is now Rt. 17, he built a brick house which later became a general store. I remember visiting with its owner, a later Abraham. It was recently demolished, hit by a crazy truck driver.
In addition to the iron works, Mr. Dater had a very fine iron mine on Dater’s Mountain just east of Tuxedo. The mine was near the top in the southern area of the mountain and a bit west of Horse Table Rock, a hangout of Claudius Smith in the Revolution. I have been in the mine, and there still looks like ore there. He also constructed a well-designed mountain road from the mine down to the main highway. Mr. Dater produced all kinds of merchant iron, some of which he sold to the Piersons who were just starting their iron business. Other items he made went by pack horse over to the Hudson and down to New York by boat.
Cole, in his History of Rockland County, gives very few dates on the Daters. He does mention an 1812 tax roll which says that Abraham had a house, farm and mountain which was valued at $4,750, (the acreage was said to be 3,000) also three forges and a grist mill on which he paid taxes of $17.50. He does not mention the furnace which I remember before it was destroyed by the Park people. Mr. Dater was listed as the third largest taxpayer in the district. He also employed over 200 people. It took 40 men to operate an iron furnace. I was told this by a man who worked on one.
There is also another angle to the Dater story. In 1797 he bought a house site In Mahwah on what was then Island Rd., and built a house which is still standing. The deed gives one of the boundaries as Dater’s mill lot. The pond and dam are still there as is one of the mill stones in the front of the Ramsey pump house. His land ran all the way down to Myrtle Ave. in Ramsey, part of the Barberies Tract.
Mr. Dater had three sons and a daughter. His eldest son, born in 1793, was Adam and who later lived In Mahwah, operated the grist mill and married Mary Young. He was my great, great grandfather. He lived only 32 years and his widow married Hassel Doremus who helped raise the six Dater children.
Mr. Dater’s third son was Abraham Adam, born in 1805, married Mary Ward of Sloatsburg. They were very active in the area; one of them ran the iron railroad that operated out of Sterlington, N.Y. late 19th century. Abraham Adam stayed with the iron business and his father made him a partner. He lived until 1877. He bought 29 acres on what is now the Piermont branch of the railroad and this became Dater’s Crossing. This was part of the main line since the state charter made them stay in the state. My great grandfather, John Y., helped build the Paterson and Ramapo R.R. which later gave the Erie a route to New York.
Abraham Adam was the immediate ancestor of the Mahwah Dators. He had a son, Francis Z. (1849-1933) who was the father of Raymond F., and he of Frank. The family lived at Dater’s Crossing and then built a house on the Turnpike in Mahwah.
