   * Matteo II. Visconti († 1355)

   * Giovanni Visconti,

unter die das Herrschaftsgebiet der Familie 1354 nach dem Tod des Kardinals Giovanni Visconti aufgeteilt wurde.

From the Pope's profile: NOTA BENE (March 14, 2017): there may be a homonym error here.

1. A certain Theobaldo Visconti, born in 1230 and also deceased in 1276 seems to be more likely the father of Matteo, father of Stefan.
2. It seems highly unlikely that the father of the Pope woud be around 10 years old (born 1200) at the birth of the Pope
3. Pope Gregory X does not show on Wikipédia lists of Popes having had children Anyone with further information and/or help in clearing this up - please feel free to contact any of us managing this profile. Thanks. MP
