So - I am a descendant from Lars / Lewis Edwards Second son - "John Lewis Edwards" (Donald Duff Edwards was the first).
I guess the next part of the puzzle to solve is his birth date - Referring to Larking crew manifest, it notes his age as 29 - hence the date of 1820 for his birth.
I am not sure it helps or misleads, but in my family circles his birthday was 1818 (nothing fixed just a oral date)
