About this webinar
Maurice Gleeson has been experimenting with Multiple WATO (What Are The Odds) Analyses as a technique to break through Brick Walls in family trees at the 1750-1800 timepoint. With Multiple WATO Analyses, all possible scenarios for an ancestral relationship are explored (hence the "multiple" in the title). So if there are 3 individuals born about the same time, the various scenarios to explore are: 1. are they all brothers? 2. are they all half-brothers? 3. are two brothers and the third a 1st cousin to the other two? 4. are two half-brothers and the third a 1st cousin? 5. are they all 1st cousins? etc. etc. etc. And each scenario above is assessed from the perspective of all descendants involved in the analysis ... so if there are 10 Scenarios and 8 descendants there will be 28 pair-wise comparisons in each scenario so 280 comparisons in total. Maurice will present several examples of how this technique has been used in practice to break thru Irish Brick Walls.

Interesting, but very detailed
Very technical, showing multiple methods which is good because genealogy does not come prepackaged with a tidy bow. Getting multiple tools to put in our toolbox in one webinar is a great time saver.
I leaerned but this is still above my head. He did a great job of explaining, I just have trouble understanding it all.
Please continue to ask Maurice Gleeson to give presentations. He is an outstanding researcher and presenter!
Maurice Gleeson always presents in a wonderful manner, and the case studies in this particular webinar were fascinating to work through with him.
Excellent information. I shall be watching it again.
Super excellent. Perfect for us "geek" types. Explained in a way that took a complex analysis and made it understandable, and not too overwhelming. Maurice has a very engaging style of presenting. I definitely will watch it again because I think I may finally have a tool that will help answer the exact same questions I have.
A lot of the information was knew and well covered. I will need to return to it and also try some of the suggestions. I'm excited and looking forward to do this type of analysis.
