'I was about to write to you, Dear Aleksander, and supplement my previous letter with more detail, when my wife gave birth to a daughter. In truth, it all happened yesterday, still I have not come to my senses yet, so forgive my brevity and accept 20 tickets for Śpiewnik.'

The daughter mentioned in Moniuszko's letter to Walicki was Aleksandra, born on 4 July 1852.
