Here is more information regarding the Cassatt-Houseworth family. According to my records, Susan C. Houseworth (b. 21 Dec 1852, d. 16 Oct 1916) married David Cassatt (b. 23 Jan 1844, d. 2 Feb 1915) on 22 Aug 1872. They had 6 children: 2 sons, George and Hubert and 1 daughter, Laura died young. They had 3 other sons: Orville (b. 18 Nov 1875, d. 2 Dec 1938), Virgil (my grandfather, b. 26 Mar 1878, d. 23 Mar 1960) and Bascom (b. 26 Mar 1883, d. 27 Jan 1955). I have a picture of the David Cassatt family (father, mother, 3 sons, and 3 rabbits) taken in front of their farmhouse. They apparently made brooms, as they were standing with the broom-making equipment and there were a number of brooms stacked around their house.
From David Cassatt the line goes back to William Peter Cossairt (b. 18 Oct 1815), Henry (Hendrick) Cossairt (b. 25 Mar 1778), Pieter Cossart (b. 30 Apr 1746, d. Jun 1781 in KY) and Francis Cossart (b. 21 Jul 1717 d. abt 1790). The Cossarts were French Huguenots who settled with the Dutch in New Amsterdam/York in 1665. Francis was the great-great grandfather of Mary Cassatt.
Pieter was one of a group of Dutch/French Huguenot settlers from the Gettysburg, PA area who emigrated to KY in 1781 (). After Pieter was killed (by Indians while picking blackberries outside the fort, according to family lore) the family moved to southern Ohio. David was a veteran of the Civil War, enlisting in Ohio.
I also found John Cossairt (b. 19 Feb 1847, d. 4 Dec 1910), David's brother, who m. Permelia Wallace Houseworth (b. 12 Jan 1857, d. 7 Mar 1937) in 1873.
