The date of Lea's birth in Amsterdam is given in multiple trees on the Web as well as in Geni as 28 October 1813.
I have just downloaded a scan of the geboorteakte from familysearch.org via genver.nl.
The Akte is dated 27 October 1813. The BIRTH is reported as happening on 26 October 1813.
I have changed Lea's profile accordingly.
