Very nice !! I think perhaps your chairs were not originally from the U.S !! They are much more in the style seen in the UK although can`t be certain !! Just in case you are wondering how these may have arrived from the UK to Texas,,back in the 1970`s there was a huge boom in antiques and prices were extremely good !! Many went to the UK and bought items like this as well china cabinets, halltrees, dining sets, and anything else they could for pennies on the dollar and shipped them to the U.S !! They went to anyone that would buy them by the trailer load !! I bought many things here in NE Texas from a warehouse when I had my shop !! Your set of 6 chairs likely had a table with it at one time !! Might be a bit earlier than 1890 as styles originating in the UK were usually later arriving here !! Look up Eastlake furniture or Charles Eastlake for some history !!
