Neighborhood portraits - multigenerations

This one involves four generations of the same family, who live in two houses on the same block.  The elder lady is mom to the guy on the right of the pic; grandma to the kneeling guy on the left of the pic; and greatgrandma to the two boys.

It's not very usual, especially in Washington DC, to have multiple generations actually living near each other. I miss that about the old continent :)
