Walter Prettejohn Pitts was born in Chivelstone (South Allington), Devon and his birth was registered at Kingsbridge, Devon between October and December 1839. He was baptised on 24 November 1839 at Chivelstone. He died in infancy on February 25th 1840. He was buried in the Pitts family plot in the St. Sylvester's church graveyard in Chivelstone. He was named after Elizabeth’s grandfather Walter Prettejohn who died on 1 January 1830.
Walter Lamble Prettejohn Pitts was also born in Chivelstone (South Allington), Devon and his birth was registered at Kingsbridge between April and June 1841. He died in infancy on October 30th 1841. He was buried in the Pitts family plot in the St. Sylvester's church graveyard in Chivelstone. He was named after Walter Lamble Prettejohn, an uncle of Elizabeth Prettejohn Pitts, who died on 7 April 1850. The Lamble family name was derived from Elizabeth Lamble who was born about 1705 and was Elizabeth’s maternal great-grandmother – her maternal great-grandfather was Nicholas Prettejohn who was born in 1690. This branch of the Prettejohn and Lamble families lived and farmed in and around Chivelstone and Portlemouth.
As were all the Pitts children, Anne Eliza Pitts was born in Chivelstone (South Allington) and her birth was registered at Kingsbridge between April and June 1843. She never married. Her death was registered at Plymouth in the fourth quarter of 1905.
The 1851 Census recorded that she was living at South Allington House with her parents and an 1862 family document re-stated that fact. Her residence at South Allington was again recorded at the 1861 Census. By the time of the 1871 Census however, her brother Thomas Harris Pitts had taken over the management of the South Allington property after the death of their father, Nicholas. Eliza was by this time receiving an annuity settled on her by her father and she was no longer living at South Allington; presumably she was to be found in Kingsbridge. In the 1881 Census she was described as the head of a household living in Fore St, Lower Knole, in the Kingsbridge registration district. She was living with her sister Elizabeth Harris Pitts. They were reported as “living off the income from interest of money”. In the 1891 Census she was still living with Elizabeth Harris Pitts in Fore Street, Lower Knole, in Kingsbridge but they had been joined by their sister Louisa Prettejohn Pitts. They had a cook and a housemaid. In the 1901 census, Anne Eliza Pitts and her sisters, Elizabeth Harris Pitts and Louisa Prettejohn Pitts were living on their own means in Plymouth.
