Vogelsang Family tree

That is fantastic. Who painted it?

I have a question. I don't have much information exept a name, spouses name and one child (myGreat Great Grandmother)

Her parents were: Wilhelm Schroeder and Maria Catherine Volgelsang married March 15, 1801. Their child was Wilhelmina Schroeder born April 30,1836 Goettingen Germany.
Do you have this person in your family and can you tell me more about my ancestors?

Thank You
Jan
