Focusing on the first page of matches (or indeed, any page) is likely to lead to disappointment.
To quote from the Masterclass:One has to start somewhere and focussing on the first page seemed as good as any.
"At Ancestry you'll typically have 10000 to 20000 matches with cousins, and of those all but about 1% will be with 'distant' cousins, ie where the estimated relationship is 5th cousin or more distant. So you might think that the best strategy might be to focus on the 1% on the basis that if you can't make head or tail of those matches, your chance of resolving the more distant matches is negligible. Wrong, totally wrong!!!"
If you don't follow the advice of those who have trodden the path before you're bound to be disappointed.
