Ann Songhurst b 1816 Cookham & Henley.Both aged 25 no children. See 1851 census for details he gave on his birth place - Brockham, Surrey. He said his children were born at Remenham near Henley where they were registered. Mary Pratt (d/o Shoemaker b 1814 Henley) is a visitor. Dwelling Remenham Hill, Remenham, Berks. Mary called herself "Auntie" and is "Head" on the 1881 census. At 71 she was the only entry - an invalid supported by the Parish. It is possible she had Henry's wife Ann living with her. Henry had died. Ann's son William and his family lived near Auntie Mary. 1901 at Swanscombe, Kent with wife Maria.
