In 1870 Miller had completed the manuscript for Introduction to the Study of Inorganic Chemistry when he fell ill. He passed it to Charles Tomlinson to prepare it for publication.

According to his obituary, Miller married Eliza Forrest of Birmingham in 1842. He died in 1870, a year after his wife, and they are both buried at West Norwood Cemetery. They were survived by a son and two daughters.

The crater Miller on the Moon is named after him.
