For a family H\mathcal{H} of graphs, a graph GG is said to be H\mathcal{H}-free if GG contains no member of H\mathcal{H} as an induced subgraph. Let \mathcal{G}_2^{(3)}}(\mathcal{H}) denote the family of 22-connected H\mathcal{H}-free graphs having minimum degree at least 33. This paper is concerned with families H\mathcal{H} of connected graphs with H=3|\mathcal{H}| = 3 such that \mathcal{G}_2^{(3)}}(\mathcal{H}) is a finite family. In particular, we show that for a connected graph
