Josiah Johnson was married to Charlotte Sweat.
They had two daughters Lucretia (Cresey) Johnson-Magee (born in 1854) and Catherine (Kate) Johnson (born in 1842) that are pictured in the Trinity Photos. They are both in a photo called The "Four Aunts" from Chuck Gassiott and a photo of Cresey & Emma Magee-Johnson.
