About this webinar

Mary Jones was female, landless, illiterate, and poor in Arkansas in the mid-nineteenth century. Her husband left her for another woman, her parents and many of her siblings left her for California, and the local courthouse burned to the ground destroying most of the evidence of her life. Mitochondrial and autosomal DNA evidence supports Mary’s inferential connection to her parents and siblings. How then do we write a case study about Mary that meets the new DNA standards.

    Thank you for offering these professional webinars to us! Inspiring!\n\nThe content was awesome. \n\nThe convoluted case study distracted from the topic being taught, how to incorporate DNA into writing a case study. Lovely study but not good for instruction. I had already read the article and still had issues fallowing the lecture. \n\nThe presentation was very interesting, but one needed some basic knowledge of DNA testing and results to fully understand it.\n\nThe presentation was very useful.\n\nThere is so much to learn about using DNA effectively.\n\nThere was a lot of information that I will be reviewing later a little bit at a time\n\nThis can be very complicated to meticulously trace back unfamiliar family members for targeted DNA. I think Melinda did a very good job of doing this and presenting it in this lecture. \n\nThis did not meet what the title says: How to write a case study for DNA. We already saw 2 webinars about the DNA standards, so this one should have been showing us how to write...putting the pieces of a written case study together. \n\nThis presentation gave me a better idea of what is required with the new standards involving DNA, than the previous presentation by Karen Stanbury. I look forward to reading the case study!\n\nThis presentation will help me continue discovering an ethical and thorough method of analyzing then presenting DNA with my case study.\n\nThis was a great follow-up to the Stanbury presentation. I'm looking forward to reading her article in the NGSQ as a model!\n\nThis was really a top rated presentation. Gave me new ideas at how to look at my research in identifying my 2nd great grandmother's parents. \n\nThis webinar was extremely pertinent for a similar DNA/genealogy situation I am studying. But I had no idea how to organize it all. This was perfect.\n\nThorough, with lots of good detail. Learned a lot.\n\nVery clear for a DNA newbie. Surprised that I was able to understand as much as I did.\n\nVery clear thank you\n\nvery clear; I like that she spoke slowly and clearly. Good case study from which to learn and good suggestions.\n\nVery clearly and thoroughly presented.\n\nvery clearly presented\n\nVery detailed and practical information for writing a case study.\n\nVery detailed material; well delivered\n\nVery good detail, this was a tremendous help.\n\nVery good info!\n\nVery helpful \n\nvery informative\n\nvery informative\n\nVery informative\n\nvery informative and well presented\n\nVery informative.\n\nVery informative. \n\nVery interesting information! Delightful presenter.\n\nVery interesting webinar. \n\nVery interesting. Thank you :) \n\nVery thorough and the diagrams were helpful.\n\nVery thorough discussion, with illustrations. \n\nVery thorough presentation. Also, addressing tree completeness is important. Perhaps there will be a future webinar on tree completeness.\n\nVery well done!\n\nVery well presented\n\nVery well-explained\n\nWell explained and documented. Very helpful.\n\nWell organized. Way above my head but I'm sure the info was most helpful for those in the certification process.\n\nWhat a special day! Thank you for this series!\n\nWill definitely be watching this several times. This was an excellent lecture loaded with more information than I could take in and process in one sitting.\n\nWow! Tremendous amount of information in this hour. Great examples and explanations that even someone with little knowledge of DNA can understand.

    Amazing amount of work\n\nanother excellent case study to help understand the process of when to use DNA from whom... \n\nAnother excellent presentation. Thank you for the examples of how to present data.\n\nAwesome job.\n\nDNA is not my interest, but I liked the story about Mary Jones.\n\nEnjoyed following the story, How do we find out if we might be related to the case study. Sebastian, Arkansas, have family there...plus several jones in my tree.\n\nEspecially like her observation concerning needing more published written genealogical information related to received DNA results to improve DNA data being able to more accurately be able to link people together with more than just probability percentages.\n\nExcellent\n\nexcellent case study requiring further review\n\nexcellent info!\n\nexcellent interesting presentation\n\nExcellent Presentation, enjoyed Melinda's thoughts and the way she expressed herself. Using common sense in applying the Standards which is very refreshing, from the usual stuffy by the letter of the rule! This was the best presentation that I attended online today! Thank you Melinda Henningfield!\n\nExcellent teaching example webinar. I like the transitional flow of the webinars today. Thank you!\n\nExcellent webinar, best I've heard on the DNA case study topic. Very clear and well organized. I look forward to rewatching this for all the things I missed the first go-round and to read her NGSQ article. Great example.\n\nExcellent! She did a great job explaining a complex topic. Her charts were especially helpful.\n\nExcellent!!\n\nExtremely informative and detailed for the hour's presentation. \n\ngood example of charts that might be needed.\n\nGood speaker that took her time and that allowed the listner to take what she said in before she went to the next thought. \n\nGood! Thoroughly enjoyed it!\n\nGreat case study example.\n\nGreat case study thoroughly explained!\n\nGreat information\n\nGreat job, Melinda! That is the type of practical information that I really needed. Thinking about my renewal portfolio and this really helped.\n\ngreat learning experience.\n\nGreat practical case study.\n\nGreat presentation \n\nGreat presentation...great tips on how to document back through time.\n\nGreat!\n\nI enjoyed the presentation. I would have liked to see tree samples and charts used in the presentation in the materials. Also, she went through a step by step process in the presentation, but is was not the focus of the lecture materials and that would have been helpful.\n\nI enjoyed this one from Melinda Henningfield I hope she comes to Legacy FT Webinars!\n\nI especially appreciated the examples of ways one might present DNA evidence in a case study. One thing I'm wondering is how judges can verify DNA information if matches won't post their results to GEDmatch.\n\nI need more DNA education to understand all that was presented. Will be doing further study of the subject.\n\nInformative presentation\n\nInformative.\n\nInformative... Thank you so much!\n\nInteresting\n\nInteresting. Fresh new info about how DNA plays into case studies. Thank you!\n\nIt helps to understand the details of what has to go into a case study, but it would if the lecturer went into more detail about what exactly a case study is and why write one.\n\nLots of great info\n\nMelinda is exceedingly thorough and logical in her presentation. I was concerned that there was too much of a repeat from Karen Stanbary's - but there wasn't. Melinda's case study was well presented.\n\nMelinda, Thank You for a fantastic informative lecture. \n\nMelinda's webinar was very thorough and detailed. Will definitely be watching it again. \n\nMuch better!\n\nNeed more of this skill level learning\n\nOMG DNA...presenter did lots of research. But I still don't understand all the ins and outs of DNA\n\nParticularly interested in detail used. \n\nPersonable, knowledgeable, but timing on some of the slides was too fast to assimilate the information.\n\nPlan to listen again; helpful with paternal relationship problem. \n\nPresentation was fascinating and well-thought out. The content only makes me want to delve further into genealogy DNA studies. Well done!!\n\nShe handled the question on tree completeness well - Genealogical Proof Standard was not adhered to.\n\nShe made this clearer than I thought she could. What a complicated case!\n\nThis was an excellent case study to show how to use DNA evidence and the new DNA standards toward certification. The graphics that accompanied the talk were also excellent.\n\nSo much good info and well presented!\n\nSo much valuable information and explanation! \n\nSpoke well, very organized. Excellent
