Ongoing research includes evaluation of Josephine Lyon (Sylvia Sessions Lyon) autosomal DNA. "Hundreds of DNA samples from male and female descendants of both Josephine Lyon and Joseph Smith have been collected and are being analyzed with the objective of identifying lineage-specific markers..." (Perego, Woodward, Journal of Mormon History, Vol 32, No.2 fn 39). Descendants of Josephine participating in this study have indicated the research is "promising" in confirming Josephine as a daughter of Joseph Smith. The researchers are also hoping to study the other possible children of Joseph Smith and welcome the involvement of descendants.
