William Martin Beauchamp wrote in 1908 that they had a "most congenial companionship" and any accounting of John's life would be incomplete without discussion of his wife.

The architect Oscar Cobb came to Syracuse and she announced that she proposed to rebuild "one of the handsomest opera houses in the country", with a capacity of at least 2,000.

[7] Wieting was involved in the reconstruction, attempting to make the opera house "absolutely fire-proof" and offering suggestions to Cobb as he designed the new building.

By July, reconstruction work was progressing well, and The Post-Standard praised Wieting as demonstrating "very rare business ability and executive capacity", again noting that she carefully attended to even minor details.

After his death, on November 28, 1900, she married Melville Augustus Johnson[13] and left New York state for a time, returning to Syracuse when he died[1] on May 29, 1909.

[15] Her estate held the opera house until they sold it to the Hemacon Realty Corporation for $1 million in July 1929.
