_Giacomo Buoncompagno_, General for the Holy Church, left many Sons all rich, and allied to good Houses; notwithstanding in a short time all was consumed: and though there was not one lavish or profuse person in the Family, though they had several Cardinalships and other Charges in _Rome_, yet could not all prevent their growing worse every day: And had not two Marriages sustained them, and put them into the condition they are in, which yet is but mean in respect of the grandeur they were in before, they had certainly before this been destroy’d. But the greatest wonder, in the particular of the sudden destruction of the _Popes_ Families, was in the House of _Peretti_ rais’d by _Sixtus_ the Fifth. That _Pope_, to immortalize his Name, and the Grandeur of his House, which was but of very low extraction, married two of his Nephews, or Nephews Sons, I know not which, into the principallest Families in _Rome_; giving each of them considerable Estates in Land, and an infinite quantity of Money: and that it might not meet with any untoward accident to subvert it, he settled their Estates in the surest and best places he could, thinking thereby to secure and establish his Family. Ten years after the death of _Sixtus_, there were seven Males of the House of _Peretti_ alive, that is, in the year 1600. all of them very rich; but particularly they which had the Inheritance of Cardinal _Montalto_, who left his Nephews an Estate of a hundred thousand Crowns in yearly Rent, besides what they had afore. Many People conceiv’d this Family was establish’d for ever; and who would not have thought so, considering the number and fertility of the Males, their Alliance with the greatest Families, their Riches, and in short, their enjoyment of all things necessary to the immortalizing a Family? Yet the Name, the Wealth, the Granduer of this House, did all vanish like smoak at the death of Cardinal _Froucesco Peretti_, who died in the beginning of _Innocent_ the Tenth’s Papacy, with no small trouble to the _Romans_, who loved his person exceedingly, having found him full of actions of generosity and nobleness to all that had to do with him. And so was the House of _Peretti_ extinct, not being able to continue half an Age. Yet notwithstanding, the death of the Cardinal was the rise of another Family from the _Pope_, which is called the _Savelli_, into which one of his Sisters was married, who remained Heir to a vast and inestimable Patrimony. Some People are confident, That if the House of _Peretti_ had continued, the _Savelli_ would have been in an ill condition; so as there was no great hurt done, to lose one Family, and have another rais’d.
