While the Canton of Solothurn seems to have been the location of the majority of early Fluri families, there were numerous Fluri or Flori families throughout Switzerland from the 15th century onward to the time of migration. The largest concentration of those not living in Solothurn was in Glarus, Schwanden. The two main lines derive either from Joss or Paulus Fluri, who were born within 8 years of each other and were probably brothers. Because there is no definite proof of this, I have listed them as "Family One" and "Family Two." vv
