My male line of Blesis is limited in that my grandfather was the only son in his generation to live long enough to have children. Likewise my great-grandfather and great-great-grandfather were the only ones in their generations to live to have children. My uncle has a son but that son has no children. I do have a son and nephews with the name. I'm looking for the nearest Blesi lines to tie into my family. My lineage chart shows a Markus Klaus Blesi, born 1932 at Basle. I believe his father was Jakob, born 1903. Also, a Joachim Blesi was born at Milano in 1916. I believe his father was Jakob, whose dates were 1875-1939. The lineage chart is not clear enough to trace these lines back to Fridolin exactly. Does anyone have family information on Markus Klaus or Joachim Blesi? If so, I'd love to share information with you. At the time the family tree was obtained from Glarus, these lines were still in Switzerland.
