I did a google search and came up with this https://ancestors.familysearch.org/en/LYJN-3DY/john-f-bracis...
Marcin and Magdelena are on the lower right side with the rest of the family
Death Date: 19 Apr 1927
Death Place: Dunkirk, New York, USA
I did a routine search on findagrave.com and came up empty. If you know which church the family was affiliated with it might help. St Hedwigs, St Hyacinth's or St Mary's. I believe some of the burial information from at least one cemetery is online (outdated)
