In the index I couldn't find a child born out of wedlock in 1816, 1817, 1818 , 1819 yet,only:
a Maria Margreta was born on 18 december 1819 Arnhem,
the record is here:https://familysearch.org/pal:/MM9.3.1/TH-266-10999-85873-48?...
The child was presented by father Hendrik Kleijn, 49 yrs. old , shoemaker, child born out of his wife Derkje Ressenaer
Are you sure about place Arhem? could it have been a place nearby Arnhem
I'll look for the birth record on that exact date you give, so I'll give it a try again.
