I found an Adam Regelski WW1 record. He is listed as living in Florida, ORANGE COUNTY, New York. His wife was Mary.
Also an Adam Regelski had a SS death notice for 1987. (born 1913)
There were telephone and street addresses For Adam Regelski in Florida,Orange,NY and also in Fredonia and Westfild, New York. They may be descendants. When Adam signed his WW1 draft notice he signed it with an X. He was born in 1879 and was naturalized. He was listed as Anton Adam Regelski.
You might post on the Orange County site or Chautauqua County site.
