1800. Genes Reunited has two trees (Susan Wordley & Keith Frost) showing a Mary Frost born 13/10/1800 in Sudbury, baptised 15/10/1800 in St. Gregory's, Sudbury [from Keith] with ancestors back to the 1600s, shown on tree above - I have satisfied myself that this is our Mary. Think her birth is also in IGI. Sudbury was & is in Suffolk.

St. Gregory's Church where Mary Frost was baptised 1800.
1818. Aug 6.Braintree. Joseph Bennett, bachelor, of this parish, & Mary Frost, spinster, of this parish, were married by banns, with consent of the parents. Both gave their mark. Witnesses were Seth Scott & John Collier. This indicates that Mary was already resident in Braintree, maybe as a servant or in the weaving industry since weaving was a part of both Sudbury & Braintree. . Also that both of them were under 21. Mary was born in Sudbury, which is 15 miles from Braintree. Could the Frosts have been weavers in Sudbury - see press articles on Earlier Frost page - and this is what drew Mary Frost to Braintree??
From here her life parallels that of Joseph. until she dies, aged 86, of senile decay, still in Manor Road, Braintree [here from 1871], 25/9/1886. Braintree Burials for 1872 onwards not held by the ERO.
Puzzle over who is the grandson, W.R. Clarke, is on her husband's page,
