[2][3] She was baptised in the now lost church of St Olave Silver Street[4][citation needed] In November 1790, she married William Clarke a portman of Ipswich who worked for the customs.

[4] The following year after becoming a widow, she married the Ipswich brewer John Cobbold, and she became the stepmother of fifteen children as well as, in time, giving birth to an additional seven.

Despite this number of children, she published under the pseudonym of Carolina Petty Pasty a poetical piece that included a portrait, which was her work too.

One of these, Nucula cobboldiae, was named after her by James Sowerby and included in Mineral Conchology of Great Britain.

[9] The Acila cobboldiae [nl], a rare species of shellfish, was also named after her by George Sowerby.
