This is from the "Continuation of the Waldo Genealogy 1900-1943" book: Eliza Waldo b. 7 Oct 1867, m. 23 Mar 1884 Henry-Franklin Butts. Parents of Eliza are Abram M. Waldo, son of Calvin (Calvin, Shubael, Edward, John, Cornelius) and Nancy F. Harker. Abram was married four times. Abram and 3rd wife Nancy are listed as having 7 children, with Abram having another 11 children by 4th wife, Jennette L. Locke. A note in the book states,
"Mr. John Anthony Waldo writes that he and his sister, Eliza, are the only ones that have any descendents. This appears to be an error so far as his sister, Nellie, is concerned. Perhaps he referred only to his own full brothers and sisters."
This is the only information I can find in these books.
