Question: When did Lucia Visconti's father die?
Sentence (from "Lucia Visconti"): HenryIV guaranteed Visconti a third of the income from her portion of her husband's lands in England, but for the rest of her life she was constantly affected by money problems, as the dowry promised by her family upon her marriage was never paid: reprisals taken against Milanese merchants in London in 1464 and 1489 were probably both related to the unpaid dowry.
Relevant evidence: No
