Help With Translation

Below is a copy of my grandfather Rubin’s birth entry but need help to translate the “Anmerkung”.

Rubin was born in Zablatow in 1881. His mother was Bruche Singer. His father was Hersch Ohling. When Rubin married in 1908, he was still known as Rubin Singer. His name was changed to Rubin/Robert Oling, possibly in 1917.

I wonder if the “Anmerkung” relate to any additional family history that I can discover from the document.

I would be grateful if this segment of the document could be sent to all list members as someone might understand the language.

Thank you and very best wishes to all.
