In all my research i find that my grandfather surname was Mak, It was changed to Mack when he arrived in the US 1899. Thats how the person at Ellis Island spelled it, so my grandfather didn't correct him, so he kept it as is.
My ancestors were of German decent and thier surnames were
Mak, Makk or Mack
Valler or Waller
Freiz or Fritz
They came from Isztimer, Paks, and Guttamasi
