Hi Ken, I think the name Shank or Shanks seems to be prevalent in the Depwade dist. of Norfolk, there is an interesting 1871 census for John Shank bn abt 1838 & amongst his family there is a boy recorded as a son but his surname is given as Miles aged 12, possibly this Walter (more than one found)was living in 1861 with Grandparents name of Kemp, however in this record his birthplace given as Redisham (Suffolk)There is a birth record for a Thomas Walter Miles at Norwich 1859. Another record that maybe ties in somehow for a girl baptised at Needham St Peter, Norfolk (close Brockdish) record gives 10/03/1863 Emma Shank MILES (no Father.rec'd.)mother Sarah MILES (poss illig.?)This could explain the lack of records for Walter, As this Walter was living in Yorkshire & probably had good Norfolk accent he would have said it similar to (Brawkdish)explaining variations in 1891,1901 & 1911, regards Frank.
