The First Ludwig
There is certain confusion about Ludwig van Beethoven's birth certificate. In April 1769, a year before his own birth, a brother had been born who had also been named and registered Ludwig. This child only lived for six days. Ludwig was born the following year and given the same name. This has given rise to a great deal of confusion, which has never been clarified. Dates used by biographers are sometimes contradictory due to this problem with the archives.
Anton Karl was born in April 1774. his godparent were the minister Belderbuch, and Countess Caroline von Satzenhofen. Johann thought that with these godparents he might have some influence on the Elector and be appointed to his father's position at court. This, as we know, did not happen.
Before Ludwig's sixth birthday, in October 1776, his second brother, Nikolaus Johann, was born.
Maria Margaretha Josepha
Beethoven's only sister, Maria Margaretha, was born in 1786. she was only one year old when her mother died.
