I am trying to research a Mary Ann Orwick b. May 21, 1830 PA, d. Jan 26, 1899 probably in Washington Twp, Warren Co. NJ as that is where she is buried with her husband George W Washburn. They were married Oct 7, 1850 most likeley in Greenwood Twp, Columbia Co. Pa.The 1850 census has her there and the 1860 census has her there with her husband and thier first 3 children: John Vinstont, Mary Rovena (poppie) and Eugene Leonard.
They had another son in 1866 - Obiah George Brinton Clellen.
Her descendents have ties toEaston, PA and Phillipsburg, NJ as well.
Happy to share what info I have on her descendents. I also believe the family was in Washington Twp in 1874 based on an Atlas of Warren Co. published in 1874, but haven't been able to find George & Mary Ann in census after 1860.
