Genealogy is really cool as long as you use reliable resources and can verify your findings. Sometimes, while maybe very elaborate and exciting, some family “stories” aren’t always right. My mom has been doing research for many years. She has been to quite a few seminars and visited the Mormon library in Salt Lake City several times. She also belongs to numerous online sites. She has verified several lines of her side back about 12-14 generations to the late 1500s. DNA is also a very interesting animal itself. My mom, 2 of her brothers, 2 of my sisters as well as myself have all submitted our DNA samples and you’d be surprised how different the results can be between full blood relatives. Good luck in your research.
