1. I am unable to find the first source and have no clue as to its reliability. If it cites primary sources for this person, then those are the sources that should be found and verified. If this is an unsourced tree, then it isn't reliable and shouldn't be used to create or support pre-1700 profiles.
2. The second source only cites WikiTree as a source for information about this person, which means it's not a source at all.
