Meaning & History
One day in Germany there was a male infant left on the steps to a church. When someone found the baby on the steps, they decided to name him Oster because that day was the day of Easter. Easter in German is Oster. Whether they added the "day" at that point or not is unknown, day in German is "tag." It is possible that someone changed it to day from tag when immigrating, or perhaps they added it. Little else is known. Feel free to help if you know anything.
