Marriage notice Jan 1846 for Robert Proctor jnr butcher to Mary Toft eldest daughter of Daniel Toft master mariner.
1851 census Robert Proctor 30 butcher, wife Mary 26, and living with he mary Toft described as mother but actually mil age 56 master mariner widow and Jane Toft sister 21.
Looks like a contender, so only need to find unmarried Mary jnr, Mary the mother and sister Jane in 1841
