Do I get it right that each graph of yours can be constructed from a 
projective 2-weight code over GF(2)?

Sage has a small database of such codes, so one can add your graphs there 
in this form.
See strongly_regular_from_two_intersection_set 
and strongly_regular_from_two_weight_code
in sage.graphs.strongly_regular_db
