A few corrections:
1. Her name did not contain "Margaretha". She was only called "Maria Magdalena" (no official documentation contains "Margaretha")
2. She was NOT born on 8 August 1733 - there is no proof of this. ONLY that she was baptized on 30 August 1733 and born before then.
3. There is also NO proof that she passed away on 1 April 1815.
