I have lots of information but not necessarily everything you are asking.On the immediate family that you are talking about the only additional information I have is a birthdate for Rowena which is 10 Feb 1917 if that is correct.
However I have a lot more on your ancestors as do several people that use this bulletin board.Your direct ancestors are as follows as I have it: J. Nickel Rapp b. Bef. 1723 Germany m. Bef. 1744 in Germany Margaretha b. Bef. 1730 Germany Simon Rapp b. 1752 Barbelroth, Pfalz, Germany d. 20 Apr. 1836 Catawba, Clark Co., Ohio m. 8 Mar 1778 in Frederick, Maryland Sarah Griffith b. 1761 d. 9 Sep 1846 Catawba, Clark Co., Ohio Simon Ropp b. 27 Oct. 1796 Loudon Co., Virginia d. 6 Dec. 1864 Union Twp. Champaign Co., Ohio m. 15 Nov 1815 Barbara Ann Demory 3 May 1796 Loudon Co., Virgina d. 11 Jul 1861 Union Twp., Champaign Co., Ohio Andrew Long Ropp b. 1830 d. ? m. 23 Dec. 1849 Urbana, Champaign Co., Ohio Catherine Hess b. 28 Nov 1830 Union Twp., Champaign Co., Ohio d. 12 May 1900 Salem Twp. Champaign Co., Ohio.
Andrew Long abandon his family sometime after the last child was born in 1864.He had seven children. There is some evidence that he may have remarried later in Wabash, Indiana but I'm not sure if that is proven. Emanuel Pearl was his third child.My Henry was his eldest child.My Aunt remembers a Great Uncle Pearl visiting her Grandparents home in Rensselaer, Indiana.Henry Ropp move there with his wife Esta Craig around 1885.My Grandfather Andrew Ross Ropp was born in Urbana on 26 Feb 1884 but his younger brother Dalton (Dal) was born in Jasper Co., Indiana on 28 Mar 1886.
If you can expet a Word document I can send you much more information.
I live in Flower Mound, Texas which is a suburb of Dallas/Ft. Worth. I grew up in San Pierre, Starke Co., Indiana and my mother Nelda Iris Ropp grew up in Wheatfield, Jasper Co., Indiana.
