After Székeles' death, Helene married Johann Kottanner, a burgher from Vienna, in 1432. During that time, Johann was chamberlain of the St. Stephen's Cathedral in Vienna. According to historian Karl Uhlirz, he has reached the age of majority only in 1426, thus Helene was approximately six years older than her second husband. Their marriage produced more children, including a daughter Catherine. By 1436, both Kottanner and her second husband were servants of Albert II of Germany, the then Duke of Austria, and his wife Elizabeth. Kottanner's role in this royal Habsburg household was nanny to princesses Anne and Elizabeth, the children of Albert and Elizabeth. Note that, according to the contemporary German custom of calling a wife or sometimes daughter, the alternative names ending in "-in" amount to adding a feminine suffix to her husband's name.
