  We study three independent pairs of Jaynes-Cummings systems such that two
atoms might be correlated with each other but the third atom is uncorrelated
with rest. We investigate the conditions under which these uncorrelated three
atoms may become genuinely entangled. We find that this task is impossible if
the cavity interacting with uncorrelated atom share classical correlations with
any other cavity. We observe that atomic state can become genuine multipartite
entangled, at least if the cavity with uncorrelated atom, is highly entangled
with any other cavity. This is an interesting and non-trivial observation and
may serve as another technique to generate multipartite entangled atoms via
JC-interactions. The findings can be realized with available experimental
setups.
