Actually most of the work was done in the 60s and by mail.The book was published in 1968 and after Dr. Nay's death his family gave the remaining books to my mother to distribute and now I have the few remaining copies and 20-30 unbound copies which I let go to Rudolph's descendant's, for whom the book has the most value.As I have told you privately, you know far more about Mary's line than I do.As I have told you, I also learned from the Kershner's that Dr. Nay's information about Mary Flenner and George Kershner was probably in error.I visited Rudolph Flenner's homestead which still stands in Butler county, OH and Carl Rupp told me and and I personally saw the cemetery where Dr. Nay thought she was buried.The stones are to worn to read any inscriptions and Carl, a descendant of Rudolph's son Daniel (his ninth of fourteen children not counting the three stepsons he raised of Magdelena Kershner Baum's first marriage) could not help resolve the issue.Rudolph had a daughter Margaret, AKA Mary who also married a George Kershner, the brother of her mother Magdalena. Her uncle in other words. Margaret (aka Mary) owned tracks of land near Rudolph's land, which was divided and much sold off after his death to settle his estate among his many children. the track maps of 1836 show a large track in the name of Mary Flener in section 4 of Liberty township, Butler,County, Ohio, although this potentially could have been his daughter Mary Magdalena's land which Dr. Nay refers to indirectly in his book in reference to the settlement of Magdalena Kershner Baum Flenner's estate in 1820, citing a Carlton Waldo as a legal heir.She didn't marry Carlton Waldo, M.D. until after the War of 1812, and was referred to as Rudolph's daughter Mary Flenner in a deed in 1811 selling land to her brother-in-law Jacob Slipher (who married Sussannah Flenner).In short, the 1836 tract maps could be referring to land she owned prior to marrying Dr. Waldo.Shorter yet I haven't figured it all out yet and perhaps never will.Keep in touch.
