The Geni profiles claim that Johannes Frederik Koegelenberg married Neeltje born in 1736 at NGK Swartland on 22 Mar 1761.

My concern is: Are the records correct in stating that Koegelenberg married Neeltje who was born in 1736 and not the younger one born in 1745? I suppose fiinding something like the DN's of these individuals shouls provide the answers.
