Were Lincoln and Ward Hill Lamon law "partners?"

[RJNorton]

Rob, I always thought this was more of an informal relationship, rather than a formal partnership. Lamon and Lincoln worked as co-counsels in many cases, but this was done more as legal associates rather than formal partners. Lamon worshiped Lincoln, so I wonder if their legal relationship...i.e. calling them partners... was really an embellishment (by Lamon) of actual fact. Perhaps Lamon told people Lincoln was his law partner when, in fact, they were really just associates in cases. I stand to be corrected on what I have said, as I am just going by my own impression of their relationship.
