"Call it a clan, call it a network, call it a tribe, call it a family. Whatever you call it, whoever you are, you need one." — British author Jane Howard

Though the definition varies wildly, family is universal. Perhaps this is why the family is such a consistent source of inspiration for artists.

This December, the Museum of Fine Arts, Boston, celebrates this universal muse with (un)expected families, an exhibit of more than 80 photographs spanning more than 150 years.

"Almost as soon as exposure times became short enough to make portraiture feasible, photographers have been drawn to capture likenesses of loved ones," said Karen Haas, the MFA's Lane Curator of Photographs. "Perhaps that power to freeze a moment in time is what explains why family photographs are so often described as the first thing one would save from a burning building."

Featuring some of the most iconic photographers of the modern era — from Gordon Parks to Nan Golden — the exhibit depicts a wide range of relationships — from twins to nuns to students — that beautifully capture the myriad forms family can take.

In exposing the intimacies of other people's families, the exhibit acts as a mirror, forcing the viewer to search the works for the emotional nuances — the baggage, the inside jokes — that define her own familial bonds.

Take a moment to reflect on your family with this emotionally charged selection of photographs from the exhibit.
