Beethoven's mother & siblings--facts?

[Roehre]

Hopefully superfluously, but one has got to be aware:

Erzbisschof-Kurfürst von Trier = Elector-Archbishop of Treves

[Fidelio]

In my research, I am unable to find the age of Johann Laym at the time he was married to Maria Magdalena. Any ideas?

Johann Laym (1733-65) married Maria Magdalene on 30 January 1763.

He would have been 30 years of age.

[Fidelio]

Beethoven's correspondence provides an essential key to understanding his works and personality. It was published between 1996 and 1998 by G. Henle Publishers. Each letter is accompanied by information concerning its origin, where it is held, etc. as well as explanatory notes. The letters are published in seven volumes (Volume 7 = index). Volume 8 (documents, subject index) is in progress.
All awaiting translation into English.

The edition of documents, the eighth and last volume of the edition of Beethoven letters, will contain non-letter written documents such as register sheets, certificates and newspaper ads from Beethoven, as well as contracts with publishing houses, property declarations, bills and minutes from court trials such as the conflict concerning Beethoven's nephew Karl. Several of these documents have not been published before.

The volume will be complemented by an extensively commented index of persons, locations and works.

In addition, volume 8 also comprises addenda and corrigenda concerning volumes 1 to 7 as well as a large index covering all published letters.
