JOSHUA JOHNSON (supposed to be from Portugal) came to Ohio in very early times, and bought a valuable tract of land in what is now Scipio township, and included the land where Harrisonville is located.  He was married twice, and of the first marriage he had one son and two daughters.  His second wife was a sister-in-law of Mr. Trickler, a wealthy farmer of Gallia county.  This marriage was favored by two sons and one daughter.  The eldest son, Isaac, went to a place near Cincinnati, Ohio; and the sisters, Kate, Mrs. McHenry, and Milly, Mrs. John Ervin.  The second son, David, married Mrs. Paton, and after a few years moved to Missouri.  James Married his brother Isaac's widow and lived where his father did.  The third daughter, Polly Johnson, was a maiden lady, taught school in Ohio and in Missouri.  She was a much respected and enterprising woman, and during the excitement caused by the discovery of gold in California she emigrated with some relatives from Missouri to the gold fields, where it is supposed that she died.
