Aunt Emma

I always heard of an Aunt Emma that lived in Eagle River, Wisconsin. Before my uncle passed I had questioned him. He said Emma was the wife of a Stanley Kramer who was a cousin to my grandpa also named Stanley Kramer. He said he came to America around the time of the first World War. He told me they had 3 children named Lucille, Albert and Dorothy. Years of searching found nothing about this family. Then this past fall my sister gave me a scrapbook of mom's wedding with all the cards she received. Three of these got me digging again. One signed Aunt Emma, another signed Ed & Lucille Benson (Kramer) and the other was signed Mr. & Mrs. C. Neill (Kramer). I then went digging in the obituary archives for those surnames combined and I found Paul Stanley Kramer, not Stanley, and he was married to Emma nee Miller and his children were Lucille Benson, Albert and Dorothy Neill. The obituary also stated he was buried in Eagle River. His grave along with Emma and son Albert and his wife are listed on findagrave in the Eagle River Cemetery. Mom saved a funeral card for Lucille Benson and she's buried in Acacia Park Cemetery in Chicago.
So I now know I have the right family but the puzzle still remains. Exactly how is he a cousin to my grandpa. According to great grandpa's obituary, he had a brother that remained in Poland so I suspect this is his son but I will have to wait until I get Paul's death certificate to be certain.
