Gee, any surprise that Smith Sr and Cowdery Sr apparently were involved with this "sect" and later Joe Jr and Oliver Jr created a sect that would ultimately have these same elements?
This group is so similar to the early church (organization and beliefs) that I've learned if you even mention them on a faithful Mormon forum, the thread gets locked immediately. The apologists simply have no real explanation or any good arguments to defend or deny that they existed and that there was a Mormon connection. The only thing they can maybe argue is that we can't be sure that Joseph Smith, Sr. was involved, but I have found very good sources stating that he was (state histories, statements from witnesses, etc., and from different reliable sources).
Looking into the "Fraternity of the Rodsmen" is remarkably similar to the fraternities that Joseph set up within his structure of the church.
Here's some more information on them:

I researched this group quite extensively at one time and have a ton of info on them (I won't bore you with all of it here

). But here's some information that I think is interesting (and brief):
After Nathaniel Woods was excommunicated from his ministry with the Congregational Church, he formed a secret religious group that included the parents of Joseph Smith, Jr. Through nongregational records the link between the Winchells, Woods, Cowderys and Smiths can be made. The evidence suggests that the occult practices that Lucy Smith openly admitted her family practiced were likely participated in by the entire set of families that formed the Fraternity of Rodmen. Mormon scholar D. Michael Quinn writes, "Such coincidence of time, place, and occult activity among these people suggests that there could have been personal acquaintance that linked them and encouraged them to participate in similar and joint occult activities.
The names of those who were "Rodsmen" or in the "Fraternity of Rodsmen" along with Oliver Cowdery's father and Joseph Smith Sr.: Oliver Cowdery, Martin Harris, Orrin P. Rockwell, Joseph and Newel Knight, and Josiah Stowell.
