Hi there fellow Derrers! It is very lonely over her in England being the only Derrer family. There are 14 Derrer's who are all directly related to me (brothers,parents,cousins, uncles, aunties etc!) We are the only Derrer's in the whole of the United Kingdom. Apparently my family originated in Switzerland, but we actually know very little about it. I would love to hear from anybody who has any idea how my family ended up here! Looking forward to hearing from a fellow Derrer soon!
