Interseting thoughts and stories here folks.Amos---Kat and I searched a bit on the net for unit info with only marginal success as I recall.
kat---Where was your grannie's family from? A lot of Ewings around here, a very BIG name...streets, schools, etc.
Peter---The story of Clements and Grant is one of the more touching episodes of Twain's life. Unique man, Mr Twain. Grant's memoirs would never have even been written and the family would have been left penniless had it not been for Twain's help. Grant finished them a very short time before his death and I'm not sure he ever saw the finished product.
