My Pa Oil by Rebus

6 clues are "Printer's Devilry". I.e. where the answer has been removed from a plausible (but not necessarily meaningful) sentence and the gap closed, taking liberties with punctuation and spacing but not changing the order of the remaining letters.

Eg: Royal Academy will only display the bet (4) Answer: STAR

Should read: Royal Academy will only display the best art.

These 6 answers have to be placed thematically in the grid. 8 other clues contain a thematically relevant superfluous word which will assist in deducing the puzzles correct title. The 2 unclued answers identify the protagonists.
