Dear Sacota (unusual first name)
Additional details are helpful, i.e. Alfred's date of birth, where did he settle, names of parents, grandfather, etc.
Do you know where in Germany he was from? It is highly unlikely someone will be able to give you current family descendants of say perhaps a brother who lived in the mid to late 1800's. So perhaps another run at it with just a specific goal might yield better results or more answers.
