Lehi and the Brass Plates. |
John Tanner knew the name of his great-grandfather, so his son, Sidney Tanner, served as proxy for his great-great grandfather William Tanner in the early 1840s in some of the earliest baptisms for the dead in Nauvoo.
Unlike the dramatic story of Lehi's family in the Book of Mormon, John Tanner and his family did not leave their original home with a record of their forefathers. John's memory stretched back to the third generation, which is as far as human memory normally goes without a written record. Although our memory may go that far, and sometimes further back based on the sharing of written records, we may know a few things about our great-grandparents from hearing stories from our grandparents, but we're unlikely to know detailed information or be able to reconstruct their families without supplementary documentation, or know much personal information about their ancestors. As would be expected, although he could remember the name of his great-grandfather, William Tanner, John Tanner did not remember the name of William's wife or parents.
