Rose Lamb was born in 1843 in Boston to a prominent family.

[1] Lamb was a student of William Morris Hunt in the 1870s.

She exhibited infrequently, but her portraits were in high demand from members of the Boston elite and she particularly excelled at painting children.

She made several trips to Europe and beginning in 1884 she was a drawing instructor at the South Boston School of Art.
