Treetotal - the family you mention are not living in a caravan on the last census, nor is Charles John a Hawker - he was a Boot Maker and Repairer and they lived in a house!!! Think you must have mixed 2 families up somehow. The birth you state for Katherine Patience - she was daughter of Charles John - and the Patience who was dau. of Joseph and Kate was born 23/10/1904, baptised 1905, and married a Joseph Trigwell. The latter were in Sussex on last census, not Suffolk. Neither of these 2 girls is born in 1901 and OP's Patience.
