Dear Barbara,

The record from YVashem is saying :
"Mojsze Waiser was born in Buczacz, Poland in 1870. He was a butcher and married to Perel nee Rozenfeld. Prior to WWII he lived in Tarnopol, Poland. During the war he was in Tarnopol, Poland."

There are other records matching your research (Weiser/Weisser from Buchach) -- see the table below

(source : https://yvng.yadvashem.org/index.html?language=en&s_lastName=waiser&s_firstName=&s_place=buchach&s_dateOfBirth=&cluster=true)

And without a first name, a date or the name of the couple, it will be difficult (for me) to say which one is the right one

Best regards
David
