What this profile needs are sources, other than Ancestry trees, which are not proper sources for pre-1700 profiles.
There are several promising appropriate sources listed after the sources section, but they could use some links to them, perhaps inline citations.
The profile of his father George likewise lists a number of interesting sources, but again, no links or other access information given.
I have added one, but for some reason Ancestry's Sharing Image function wasn't working.
