How are these families (Muzzy, Brown, Rowe) connected?

Question

I have found a cluster of matches on 23andMe, 3 of which share a common ancestor in Samuel Muzzy (1795-1858), through various lines of descent, and 3 of which all descend from Richard D Brown (1796-1879) and Charity E Rowe (1822-1880). Since they are all matches to each other as well (all on the same segment), it follows logically that these two families are connected, but I have thus far been unable to determine the link. I would greatly appreciate another set of eyes on these family groups to try to find the missing link.
