Day at the beach, German style

It's a day at the beach with relatives in Berlin. Since my grandmother is about 5 years old, it was taken somewhere around 1925-26. I believe these are her mothers relatives. I was thinking it was taken on the beach near the lake in Berlin, but it could have also been taken near the Baltic Sea on Holiday?

 I have found fascinating documents since starting this blog. My great grandmother had several siblings from August Mannewitz and Berta Therese Anna Lange. It was a surprise, since I thought she was an only child. Another person that I thought was an only child was my great grandfather on my Opa's side.His name also Paul Stapf. I found a marriage certificate of a Friedrich Albert Otto Stapf with Paul's parents name on it! What a find! He died in 1941 in Berlin and I do not know if he and his wife Anna Bertha Lisbeth Kolhoff had any children. The search will continue though. My Opa as far as I know was the last Stapf from his line. Oma and Opa had a son but he past away when he was 18 months old from a freak accident. Hot water had scalded him when he reached for a pot on the stove. There had to have been an underlying issue as to why he died besides having hot water spilled on him. Of course I guess shock would have been the cause of death. Mental note to look at that certificate.

I have seen other families photos from Germany that seem to have similar photos. There was a site where a fellow posted his Oma's pictures online. They were so similar in area and time, that I felt like I was going to find my Oma in his pictures. He had class photos and one very similar to this beach scene. That site no longer is available. Such a shame. I truly enjoyed looking at those Vintage photographs. Hope I find them again.
