I am currently researching Frederick Lingg (1841-1918) who is a member of my wife's family. Mary Cody (Fred's niece and possibly the sister of William "Buffalo Bill" Cody) resided with the Lingg family in Philadelphia, PA based on family accounts. These family accounts also include visits by "Buffalo Bill" to see his sister. The 1880 & 1910 US census indicate that Mary would have been the approximate age of Mary Hannah Cody (Buffalo Bill's sister). I am looking for any additional information to identify the Lingg/Cody family connection. Any assistance would be greatly appreciated.
