Just an update to the previous post.
David B. Ewan was 50 years old when he married 23 year old Hettie J. Sweeten (or Sweeden)on May 29, 1879 in Camden, NJ. His parents are David Ewan and Rachel Bozarth. Hettie's parents are Bishop Sweeden and Mary Ann Peacock. Any further info folks may have is greatly appreciated. I will keep digging as well.
