Hi Cheryl,
Yes, I have his marriage in 1951, his two children, and his death in 2009.
What you mention about the 1943 entry seems very interesting. Thanks for that. Does it give us any other information? Unfortunately that's purely image-based, no transcription and so I can't read it myself.
Searching for Bronislaw rather than Bruno on FamilySearch, came up with a lot more this time, but still nothing that seemed relevant. There was a guy in Italy, and then most of them were based in the US with all kinds of spelling tangents and variations on the surname.
Again, thanks so much for your help with this, very much appreciated.
