The arms of Singe, of Bridgnorth (from Millington of Catstree).

There is indeed an heraldic pun (canting arms) here, but it isn't for the name Singe, it is a brilliant pun for their original surname Millington. The family that bears these arm, famously the ancestors of the Synge baronets and the celebrated Irish playwright John Millington Synge, originally bore the surname Millington.  The three millstones (each charged with an iron mill-rind) are a direct visual pun on the "Mill-" in Millington. On the crest, the eagle's claw emerging from a coronet, along with the second and third quarters of the full coat of arms (which depict a double-headed eagle), reflects the second half of the name, "-ington," representing an estate or farmstead, often associated with birds of prey in this lineage. 

The name change is a famous piece of family lore. The lineage traces back to the 16th century to a Thomas Millington, who was a choirboy at Bridgnorth. King Henry VIII reportedly heard him sing and commanded that he be called "Singe" instead. The family adopted the surname Synge (pronounced to rhyme with "sing") but rightfully kept their ancestral, pun-filled coat of arms.

Antiquaries write that the Synge family originated in England, tracing their male line to the sixteenth century in Shropshire, where Thomas Millington was known as 'corruptly* called Singe of Bridgnorth'. 

*Historically, the phrase "corruptly called" (or corruptè dictum in Latin) was used by ancient and medieval scholars—like cartographers, historians, and chroniclers, to indicate that a name, place, or term had been mistakenly altered over time. It meant a word was mispronounced, misspelled, or misunderstood.
