Ex-Lieut. Gov. John Dougherty came to this part of Illinois in company with his parents, in the year 1811.  Like most of the immigrants who came to Illinois that year, they were flying to the hills from the great earthquakes.  John Dougherty was of poor parents, and when a lad was apprenticed to a hatter to learn the trade, at which he worked for some years.  He married the daughter of George James, and lived out a long life among the people of Southern Illinois, practicing law, and fulfilling the many arduous duties of a politician and office-holder.  He was State Senator, Circuit Judge and Lieutenant Governor, besides filling several minor positions of trust.  His politics was intensely Democratic until after the breaking-out of the war.  In 1860 he was a candidate for a State office on what Judge Douglas called the Danite party's ticket.  This party was known in Illinois as the "Breckenridge party," and they bitterly opposed Douglas, because his Democracy was "too weak on the slavery question."  Out of  nearly half a million votes, Dougherty got something over 4,000.  The election over, he issued though a Cairo paper an address to the world, reading Douglas and his quarter million of deluded followers out of the Democratic party, and solemnly warned the approaching Charleston Convention not to admit the Democratic (Douglas) Delegates from Illinois.  Mr. Dougherty attended the Charleston Convention, and it is said, made from the steps of the hotel, after that convention had dissolved, a most able and fiery address to the Southern people on the subject of the state of the country.  He ran upon the Republican ticket for Lieutenant Governor, and was elected and served out his term with great fidelity to his party.
