My great great grandfather John Sibbald lived in Cohoes in 1860 and died young around 1865. Family lore has it that he invented some kind of flooring material, either a parquet flooring, or some kind of linoleum type of material. He may have moved to Troy or Albany. Has anyone heard of any kind of flooring manufacture in the Albany/Troy/Cohoes area around 1860-65? Mark Dionne Newton, MA
