baptism - parents Richard Henry and Agnes
Robert Edward baptised 14th feb 1900 Folkestone,Kent
Richard Harold b 1896 in Blackley,Manchester - in Folkestone in 1901 census
there is an Eva Binfield b 1894 Chorlton,Manchester - in Folkestone in 1901 census - she looks to be a sister ?
you need to look at the 1911 census in Elham,Folkestone as Shaun J has suggested
Agnes (Lee) Binfield is 41 born Manchester - so born 1869/1870.....
there is ONE Binfield in the Folkestone phone book
www.192.com has their address - might be worth writing to them ?? might be a descendant ...do you know if all the family left for NZ or just Robert Edward Binfield and Richard Harold ?
