Hi, My great grandmother was Mary Ann Hurrell, youngest daughter of the above parents. The information you have about the Hurrell family seems to agree with min, but there are 2 daughters - Elizabeth (born approx 1842 (ie between Phillip & John, and Mary Ann being the youngest of 5 children - born 1851.
I found an 1851 census record for St Andrews parish of Plymouth, Devon which shows all of these family members.
