Where did Robert Bunsen live?

Robert Wilhelm Bunsen lived in Germany and is actually related to me. In my family there was supposedly a family argument when part of the family went to the US. The argument was about whether or not to drop the "n" off of Bunsen to make it sound like Bunse. i guess they wanted to do that because they went to America and the names sort of change. Robert wanted to keep the n so he kept the n in his name. I am 14 and a boy and believe it or not he is my great great great many more greats something and i am going on ancestory.com to find out if he was my grandpa or uncle or whatever. but i am related to him. i am into inventing and science my self also. he never wed or had kids. i love him very much.
