There are no known pictures of two American presidents’ wives: Martha Jefferson and Margaret Taylor.

We have one silhouette (left) of Jefferson, who was a little over 5 feet tall and had auburn hair and hazel eyes.

And one 1903 book contains a suggested likeness of Taylor (right), who was described during her life as “a fat, motherly looking woman,” “countenance rather stern but it may be the consequence of military association.”

But no portrait of either woman is known to exist. Some artists have attempted renderings based on pictures of their daughters, whom they were said to resemble, but that’s the best we can do.
