Alex, nicely written. You have extensive footnotes, which is great. However, there needs to be special attention to sourcing the key data -- births, marriages, deaths -- what is the source for his birth year and place? That needs an inline source or other explanation. Also it would be helpful to have a sentence or two about his name, because I think he went by different names at different times, or at least others have identified him by different names. Evertsen? Terwilliger?
Earlier in the history of the profile, as found on the changes list, there were subheadings under biography -- ===Name===, ===Birth===, ===Marriage===, etc. Many of us find these very helpful both in spotting the information we're most interested in at one point or another, and in seeing that it's been covered.
Now, if I could just find the key data that would link my Terwilligers to him, he would be my ancestor!
