Sorry, William O'Conner was the trapeze artist, Whilhelm was his father who Married Kathleen O'Conner. Not sure what Whilhelm surname was, my mother thinks it was something like Stutts or Strutz, he changed it during the war to O'Connor. Have no idea about marriages as i cant find anything. this is my last hope as ive exausted all avenues. recaluated William was born 1901.
