Parafree groups are groups that are residually nilpotent and have the property that their quotients by the terms of the lower central series are isomorphic to the corresponding quotients of a free group. We introduce three new families of non-free parafree groups and discuss limitations to a natural procedure for distinguishing these groups from each other.
