There are two issues here. In order to create a pre-1500 profile you need a pre-1500 badge. And you need to use contemporary or near-contemporary sources. Trees on familysearch, ancestry or Find a Grave are not reliable sources. Parish records, wills and photos of tombs or memorial brasses are good sources.
There isn't enough evidence to say that the Thomas Pretty shown in 1500 is the father of the one whose will was proved in 1583. But you could make Research notes to include that information, which would be useful for further research.
