My Great Grandfather's sister, Anna Kurpil, married Onofer Boberski sometime in the early 1900s in Sayreville NJ, where they had three sons, Stephen, Nicholas, and Walter. They were still in Sayreville in 1920 for the census. I cannot find them at all in the 1930 census, and in the 1940 census, they had moved to Parksville NY to live near family, but Anna had already passed away. I have some information from a family friend that she died around 1931 and that was most likely after she already moved to NY, but my search hits a dead end there. I cannot find any death record, grave site, obituary or anything. Does anyone know anything that might help me or does anyone have advice on where I might look? I would greatly appreciate any help. Thank you so much!
