Thomas Harris married Mary Kemp with the marriage recorded in the civil registers for Stockton district as taking place during the December quarter 1907.
The civil birth registers for Stockton district record the following children with the mother's maiden name of Kemp:
Mary M Harris -- March Qtr 1912
George W Harris -- June Qtr 1914
Alfred Harris -- December Qtr 1918
Doris D Harris -- June Qtr 1920
Richard Harris -- March Qtr 1922
Susan Harris -- March Qtr 1924
Ernest Harris -- September Qtr 1925 (death recorded the same quarter)
Lawrence Harris -- September Qtr 1926
Kenneth Harris -- September Qtr 1928
Joan Harris -- March Qtr 1930
Margaret Harris -- June Qtr 1935 (she was in the family home when the 1939 National register was taken, her DOB is shown as 16 April 1935)
Although the 1939 National Register records a Clifford Harris in the family home, there is no trace in the civil registers for a birth in 1919. There is a Clifford Harris registered in the Stockton district registers in the June Qtr 1918 but the mother's maiden name is shown as BOE. There is also a Clifford G Harris registered in the December Qtr 1920 but the mother's maiden name is shown as RIGG. This leaves a question of who was the Clifford Harris in the family home when the National register was taken.
