Here, we announce four contiguous and two high-quality draft genome sequences of six actinobacterial strains (Blastococcus, Georgenia, Nocardioides, Allobranchiibius, Yimella, and Williamsia) that were isolated from rock samples obtained from Indian historical ruins and colonial building stones in New England, United States. These new sequences expand the genome datasets recovered from stone-dwelling microbes and will allow the prediction of their potential role in the stone microbiome.
