Lee - There are THREE separate types of Subscriptions - to Geni, to MyHeritage, and to MyHeritage's Data Subscription.
Neither a subscription to Geni Pro nor a subscription to MyHeritage' Premium Account will give you access to MyHeritage's records. For that you need a subscription to MyHeritage's Data Subscription. (to buy it directly from MyHeritage, rather than thru Geni, you would have to first create a MyHeritage Account - but you do not need a Premium Account (pay) - Free Account will do. Think if buy the Data Subscription from Geni's Ad, it automatically creates the Free Account for you on MyHeritage with same e-mail as you use in Geni, as well as ).
