The stork could have come to the house in our ancestors days. Your Mom could have been in a family way or expecting. Today we don’t need a stork because babies come by magic through the front door. Mom’s get driven away and come back from the store with a baby. They could have picked one out that wasn’t so loud.
Searching for records about stork visits may not be as simple as the if the baby shows up at the front door. There is a difference between types of records and maybe there is no record at all. What if your grandfather was born on the farm? My bio-dad was born on the farm and there was no record. However, he did qualify for social security. But you need a birth certificate to get a social security card? In other countries it could be even harder to find records, we have it easy in America. A record of live birth is a way for a person to get a social security card if they do not have a birth certificate. You typically need to have an idea where you were born and someone standing beside you to vouch for you. In my case my brother went with my bio-dad to the recorders office and said “this has always been my Dad”. If only the stork keep records our job would be easier.
