Yrs, and lovers, and very few scruples. This is only historical information from a book, not cut and paste.
The first pope to have a child- at least the first that we know of- was Saint Hormisdas in the sixth century, once a happily married man, heard God's call late in life. His son Silverius, become pope in 536, thirteen years after his father's reign ended.

You may be interested in the lewd, salacious adventures of the naughty popes, and there are plenty of those. The worst popes, in terms of morals, ethics, and criminal behavior, held power during the fifteen and sixteen century. Pius II, pope from 1458-1464, wrote love poems and fathered at least two illegitimate children while traveling on diplomatic missions for the church.

Indeedly, and why not. Having children is NOT sinful whatsoever.

The chastity thing with priests is 100% to stop offspring possibly making inheritance claims on church property, and nothing whatsoever to do with the Bible.

No it isn't, and I mean cant they just do something like draft up a legal document that a priest signs saying there offspring can't make those claims.

Pope Alexander VI, father of three sons and a daughter, Giovanni, Cesare, Goffredo and Lucrezia, must surely have had the most infamous papal children.
