Prussian Minister during American Civil War?

Question

Baron Friedrich von Gerolt was Prussian Minister to the United States throughout the Civil War, and was a close friend of Abraham Lincoln's.

I read that Lincoln's son, Robert, was madly in love with the Minister's daughter who subsequently broke his heart when she married one of his rival suitors.

Does anyone know the name of the Prussian Minister's Daughter?

Thanks in advance!
