Happy Birthday, Fratello mio!
Oh, if you're surprised about the slight difference in spelling of the surname - he is my brother alright! The difference comes from the fact that our grandfather thought Dreyer with a Y looked snappier than just with an ordinary I (to which view I fully subscribe, of course). So he started spelling it that way, regardless of what the spelling was in the official documents. My dear brother, regularly Swiss that he is, reverted back to the official spelling again for his family branch. Interestingly though, my official documents, for the first time in family history, are all spelled with a Y - so I guess that will be a challenge to future genealogists!
