While you did not indicate how long your daughter was married, ( I suspect it was a short time )from what you say there is little question your daughter's marriage was properly annulled by the Church. The problem does not arise in such cases as yours, but in marriages of many years, many children, and much parish involvements. (CFM, CCD etc)

5 years. She did not give up on him easily. He was a sociopath. When she finally threw in the towel (after he said he really didn’t want to be married) his parents said, “We’re surprised that you didn’t give up on him a long time ago. We’re amazed that it lasted this long.” No children for the reasons stated above.

Marriage is not defined by longevity or offspring. I don't wake up everyday and wonder, "Gee, it's been eight years. Am I married yet?" Marriage either occurs, or doesn't, when the vows are made between spouses. They are the dispensors of their own sacrament. The priest is a witness and provides the blessing of the Church, but he does not administer the sacrament.

You could have 18 kids and be share wedding rings with someone for decades and not be legitimately married in the first place. If it's determined that the vows were valid, no amount of "irrenconcilable differences" afterwards can in-validate those vows.
