Some of the subjects De Jongh painted and some owners his work, can be identified from the excerpts of auction catalogues at the Netherlands Institute for Art History (RKD) in The Hague. The Haarlem artist Cornelis Dusart had two pieces by him, as "The Archangel Michael and Hagar and Ishmael in the Desert by Frans de Jongh" were among the items auctioned from his estate in 1708.[7] Frans Decker, a Haarlem painter who produced mainly portraits, owned three pictures by De Jongh. His estate, which was sold in 1752, included The Adoration of the Magi, Tobias and the Angel, and a piece described in the auction catalogue as:

Claudius Civilis met de bevelhebber der Romeinen in samenspraak, zeer fraay, door F. de Jongh, daar in zijn eigen Pourtrait.

Claudius Civilis conversing with the commander of the Roman army. Very beautiful. By F. de Jongh, whose own portrait is in the picture.[8]

The Haarlem artist Jan van der Vinne had a painting by De Jongh of Minerva Calling on Envy, which was auctioned in 1754.[9] From the provenance of these six pictures, it seems that De Jongh's work appealed mainly to Haarlem artists.
