The chair seat is made from one solid piece of wood with the grain running side to side, rather than front to back and pieced together like later construction, indicating that it is a mid 1800s design. The really early Windsors had the legs go right through the seat and were more elaborate, and detailed with twice as many spindles.
I have the ads that Mr Ward placed in his prime in the 1850s. There was much about him in the local papers and in the 1860 census and then the trail ends abruptly. His wife is shown living in a home in 1870 apparently alone. A map shows the house as "Mrs L Ward." I even know the names and ages of his children. I emailed the secretary of the Wawayanda lodge where he was also secretary in the 1850s and also I emailed the Head of the Piermont Historical Society, but neither replied.The person I bought it from new nothing, but how much more do I need to know at this point? He was born in 1827 and was living in 1860 at 33 years of age. Wife named Jane P Ward and 4 children. He was a merchant of tin and iron products and had a couple of business partners at times named Auryensen and Demarest. He took over the business from one of them (Auryensen) in 1853 according to an ad regarding who to pay bills to from that point forward.
The desk was purchased in a thrift store in NJ the same week. It wasn't part of that deal. It is a Sheraton style writing desk, like you said Mart, from the mid 20th century. It has faux burl drawer panels and oak dovetailed drawer sides. The top is black, hard and textured like leather but I think it is a fake finish. It is, fortunately, in good shape and a quality piece. I use both pieces together for writing on the internet until the hard seat gets to me. I need to find a cushion for the chair. I love the brass details on the desk legs.
