It's interesting that he signed it with "as" and the 1940's census that way. In the 1930 census, it was listed as Gukas which is also strange. I will call my grandfather tomorrow and ask what the deal is. I remember I asked him when I was quite young why his brother's name was spelled that way on the military items and he said it was listed incorrectly or something to that effect. It is funny because you will never find another mention of any of his siblings having the last name Jukas after that 1940 census. His older sister Frances born in 1923 Kaska, PA died at 85 in 2008. The obituary listed her as Frances (Jukus) Urbanowicz, daughter of John and Frances Jukus. It lists all of her siblings including John Jukus (it states he died in WW2 ) and Bernie Kozla who was mentioned as a grandmother of a previous poster on this forum. Frances was my father's aunt and lived in the town next where I grew up in New Jersey. Here is a link to her obituary: Frances Urbanowicz's Obituary on MyCentralJersey As I mentioned, John's younger brother Raymond Jukus passed this year and his obituary lists my grandfather Leonard, Norman, and Jean as his living siblings. All of them are John's siblings. Raymond Jukus, Saint Petersburg | Florida USA Obituaries Also, if you check out this page on familysearch, you will see all of Frances' siblings listed (sisters with their married names) and all her brothers as "Jukus" including both her older brother John and her father John. All of the siblings match the 1940 census. Frances Jukus Urbanowicz, "United States, GenealogyBank Obituaries, 1980-2014"
