Given a finite graph $\Gamma$, the associated graph braid group $B_n(\Gamma)$ is the fundamental group of the unordered $n$-point configuration space of $\Gamma$. Genevois classified which graph braid groups are Gromov hyperbolic and asked the question: When do these groups arise as $3$-manifold groups? In this talk, we give a partial answer for $B_3(\Theta_m)$ where $\Theta_m$ is the generalized $\Theta$-graph.
