This is probably Mahala's "new" family in 1871,in Grimsby:
William Price (or so its indexed ), head, mar, 36, Labourer **** Yard, London
Mala, wife,32,Horncastle
Sarah, 8, Louth
George,4, Grimsby
William,2,Grimsby
The names correlate with 1881 and 1901 censuses for Mahala (found it by searching any George born Grimsby 1867 + or - 2....based on the 1881 entry)
Suggests that Thomas was indeed off the scene by 1871
