Wach, Elisabeth Mendelssohn Bartholdy, 1845-1910

Wach was married to Elisabeth (Lili) Mendelssohn (1845–1910), youngest daughter of Felix Mendelssohn. They had six children,[4] their son Hugo Wach became Professor for architecture and ornamentation at the Technical University of Berlin.[1] Felix Wach, father of Joachim Wach, became a jurist and Saxon public official.[4][5] The Wach family preserved the heritage of Felix Mendelssohn in a collection of letters, furniture and objects of art.[3][5]

Mendelssohn married Cécile Charlotte Sophie Jeanrenaud (10 October 1817 – 25 September 1853), the daughter of a French Reformed Church clergyman, on 28 March 1837.[97] The couple had five children: Carl, Marie, Paul, Lili and Felix August. Lili married Adolf Wach, later professor of law at Leipzig University.[100]

The family papers inherited by Marie's and Lili's children form the basis of the extensive collection of Mendelssohn manuscripts, including the so-called "Green Books" of his correspondence, now in the Bodleian Library at Oxford University
