I have been hitting dead ends finding information on Joseph Szplit born in Poznan, Poland, Germany in 1862 and died in Chicago, Il in 1910. The 1910 Census gives their address Marshfiield Avenue. All the children are dead and I am not in contact with the cousins. I remember My Aunt Ann had a note book of his that showed him experimenting with spellings of the name Szplit or Splett. I was too young to think to ask questions.
He and his wife Eva arrived in America in 1886 and had a grocery. Some relatives spell the name Splitt. There are Splitt in the area but I do not know if they are distant cousins.
