Hi. my name is Felipe Apeldorn and i'm from Sao Paulo - Brazil. as you can see, i have the same last name as yours. I know a little bit of the name, but my family is from Germany. You said that you are not sure about where the name is from, so I decided to send you a message. Please answer me, too. Sorry if there is anything wrong in the message, but i don't know English very well.
