Jarvis preferred the use of female voices for his setting of an epitaph to Miss Mary Bennett (some sources say Basnett), daughter of Thos. and Anne Bennett, died 10th February, 1756, aged 23, whose tombstone was situated in the churchyard at St Pancras (Middlesex).

Blind from birth, Jarvis was latterly employed as organist at the Foundling Hospital, and at St Sepulchre without Newgate.

Lyrics: Anon

Go spotless honour and unsullied truth,
Go smiling innocence and blooming youth;
Go female sweetness joined with manly sense,
Go winning wit, that never gave offence;
Go soft humanity that blest the poor,
Go saint-eyed patience from affliction's door;
Go modesty that never wore a frown,
Go virtue and receive thy heav'nly crown.
Not from a stranger came this heart-felt verse;
His pen inscrib'd thy tomb whose tears bedewed thy hearse.
