There were fewer people then, but they huddled together. Eleven souls once lived in this tiny house, which consisted of one room downstairs (a bed, a hearth, a table) and a cramped stairway to the second floor. There, scads of islanders were born — including the mother of an old woman I met the day I visited this place, the oldest house in Chincoteague, Virginia (circa 1795).

Meanwhile, there are only three of us now in a once cramped center-hall colonial that is ever more roomy as the children move out. And we are one of the smallest houses around. Nearby neighborhoods are filled with McMansions, their two-story foyers and three-car garages of a different heft and scale than the houses here.

What sort of people does crowding create? And what sort of people emptiness? I re-charge in solitude and would probably have been driven crazy by the cheek-to-jowl existence of my ancestors. But still, there are times when I feel a deep-boned loneliness that’s not so much personal as evolutionary. Maybe it’s the crowded rooms of the past that I miss, the intensely shared life that never let us forget that we’re in this together.
