What a sad situation for everyone, and I understand why a parent would attempt to find answers on a forum such as this one.
As pointed out earlier, some wolves hide in the SSPX, R&R, and sedevacantism. It seems to me that the wild-west of sedevacantism where tracing who consecrated which bishop and who ordained this priest is a dizzying path makes hiding easier. Some sedevacantist priests who call themselves independent and will offer the information of their ordination freely, but what if they are lying? There are also sedevacantist priests in the U.S. who claim to have a bishop in Mexico, or Europe and language barriers would preclude a concerned parent from making contact. Traditionalists on this forum have a wealth of knowledge and as trail-blazers and can say who is safe and who to avoid.
Therefore, we cannot judge the intention of a person asking about this or any other Traditionalist priest. If we know with certainty about a priest's character, we should comment.
Finally, if you do not know the person in question, refrain from commenting on the thread.
It would be irresponsible of a parent not to make inquiries about any adult their child comes into contact with at church, school, even their doctor.
