I would not recommend going to Bp. Dolan. There is a lot of evidence Archbishop Lefebvre only imposed one hand on him instead of two. I definitely suggest reading this article.
This nonsense has to stop ... another Kellyite smear.
Eastern Rites only impose the right hand in the ordination of a priest, and the Roman Rite Missal for several centuries also indicated the right hand [dextram]. I believe that the confusion arose from the fact that at a priestly ordination the other priests in attendance at one point also place their hands on the ordinand's head. But, again, a single right hand is all that's required for validity.
To this day, the Kellyites conditionally confirm even those who have been confirmed by Bishop Williamson, because Bishop Williamson also had one hand imposed, as he was in the same ordination class in 1976.
It's one thing for you to be constantly driven by scruples, and quite another to be spreading this stuff around.
