Wilhelmine Jauch (1809–1893) married Theodor Avé-Lallemant, from his maternal side a descendant of the Huguenot leader in the French Wars of Religion Gaspard II de Coligny (1519–1572).
Avé-Lallemant was a musician, music-teacher and music-critic.
His wife's wealth enabled him, to become after getting married an important promoter of the music and to play for almost half a century a leading role in Hamburg's music life.
He was until his death the chief director of the Hamburg Philharmonic Society (German: Philharmonische Gesellschaft).
In 1841 he organized and directed the 3rd North German Music Festival in 1841 in Hamburg, which was the biggest festival of its time.

Hans von Bülow dedicated to Avé-Lallemant his Chant polonais Opus 12.
Klaus Mann describes in his novel Pathetic Symphony (French: Symphonie Pathétique) about the life of Peter Tchaikovsky a meeting between Tchaikovsky and Avé-Lallemant.
Tchaikovsky dedicated to his admirer Avé-Lallemant, for whom he had a lot of sympathy, his 5th Symphony.

First of all I should mention the chief director of the Philharmonic Society, the aged Herr Avé-Lallemant.
This most venerable old man of over eighty paid me great attention and treated me with paternal affection. ...
When I then visited this kindly old gentleman, who passionately loves music and who, as should be obvious to the reader, is quite free from that aversion which many old people have against everything that has been written in recent times, I had a very lengthy and interesting conversation with him. ...
We parted as great friends.
